A hypothetical model is built to explain an in-band distortion mechanism of the class F amplifier. Using the model it is analytically proved that static non-linearities of switching amplifiers do not cause meaningful in-band distortion when the amplifiers are driven by ideal 1-bit digital RF signals. It is also found that short-term memory effects significantly contribute to in-band distortion. The ...

We ...

  • Analysis on in-band distortion caused by switching amplifiers

    A hypothetical model is built to explain an in-band distortion mechanism of the class F amplifier. Using the model it is analytically proved that static non-linearities of switching amplifiers do not cause meaningful in-band distortion when the amplifiers are driven by ideal 1-bit digital RF signals. It is also found that short-term memory effects significantly contribute to in-band distortion. The analysis and the mechanism are tested and supported by MATLAB simulations. A system composed of a field-programmable gate array and a class F amplifier has been built and the in-band distortion mechanism is verified by measurement.

  • Parallel operation of switching amplifiers driving magnetic resonance imaging gradient coils

    The paper presents a high-current switched driver for gradients coils used in magnetic resonance imaging. The proposed solution driver consists of two 1 W, 2 A amplifiers in parallel. The successful parallel operation of these drivers requires good current sharing during steady state, as well as transients. In addition, MRI system performance requires a bandwidth no less than that of each single driver, and no loss of voltage to drive the gradient coil. To ensure good current sharing only by control means results in an amplifier with unacceptable transient response, either too slow, or with oscillations. A coupled inductor at the output of the amplifiers is the preferred option. The coupled inductor offers the additional option of operating the two amplifiers out-of-phase to reduce the output current ripple with minimal impact on the inductor size. The paper presents the analysis and simulations for all the options, and the design of the coupled inductor for the selected solution. The experimental results in a system prototype confirm the design selection and show the system performance at high currents.

  • Importance and measurement of phase-stiffness in RF switching amplifiers

    Phase-stiffness is a measure of the ability of an RF power amplifier to tolerate disturbance injected into its output. Phase-stiffness of conventional (linear) RF power amplifiers used in phased-array radar results from inserting circulators and isolators on their output as they can not tolerate typical disturbances arising from antenna mismatch and signals arriving from mutual coupling of array elements. We show that the output stage of a RF switching amplifier employing a single AlGaN/GaN HEMT loaded with an inductor exhibits high tolerance to external signal disturbance at the carrier frequency. This RF amplifier architecture shows promise for use in phase-array radar and active antenna array transmit/receive modules as this may operate without isolators.

  • Digital correction of PWM switching amplifiers

    Pulsewidth modulated (PWM) signals for driving a switching audio amplifier can be synthesized in the digital domain with extremely high linearity and precision. However, nonidealities associated with the power stage degrade output performance. A method to digitally correct for these nonidealities, resulting in very low total harmonic distortion (THD) and high signal-to-noise ratio (SNR) performance, is presented. This method also provides excellent rejection of power supply noise which is otherwise absent in digital PWM amplifiers. To meet noise requirements for hi-fi audio, the feedback structure is a fourth-order structure which shapes the noise beyond the audio band. The method has been implemented on a bread board, and state-of-the-art performance was achieved. Total harmonic distortion of 85 dB and dynamic range of 100 dB was measured using Audio Precision test equipment.

  • Superconducting Switching Amplifiers for High Speed Digital Data Links

    In a superconductor digital-RF transmitter, the power amplifier chain can be implemented in hybrid temperature, hybrid technology environment, where the superconductor switching amplifier forms the first stage of the amplification chain. We have designed several flavors of SQUID based switching amplifiers, each targeted for different power output and speed. One of the amplifiers is a differential amplifier featuring dynamic equalization. To minimize the intersymbol interference, the amplifier employs a pre-emphasis technique, thereby compensating for the bandwidth limitations of the channel. The differential output voltage of this amplifier is 16 mV at low speed (200 Mbps), which rolls off to 2 mV at 16 Gbps data rate, for an ldquo1100rdquo pattern (no consecutive transitions on the input data sequence). For high speed operation of the SQUID amplifiers, simultaneous switching of SQUIDs is desired to reduce the output rise and fall times. Hence, in another amplifier design, called the Differential H-Tree Amplifier, the SQUIDs are arranged in an ldquoH-treerdquo structure, to equalize the propagation delay of the control signal to each SQUID. The amplifier's differential output voltage is 8 mV at low speed (200 Mbps), and rolls off to 2 mV at 10 Gbps data rate. A third type of amplifier is a differential SFQ-to-DC amplifier; it consists of a pair of synchronously driven SFQ-to-DC converters that produce complementary positive and negative voltage waveforms respectively. The differential output voltage of this amplifier is 0.8 mV, and it can be operated at very high speeds. Moreover, the complexity of this amplifier enables it to be yielded in higher critical current density process. Both, the speed and the output voltage scale as the square root of the process critical current density.

  • Switch-mode power amplifier linearization

    A continuous time band-pass delta sigma modulator was designed and fabricated in a 0.18 mum SiGe BiCMOS process. This IC was designed to accept an analog intermediate frequency input up to 100 MHz. A synchronous clocking scheme was incorporated to perform frequency translation, in addition to quantization, inside the modulator loop. The modulator was inserted into a closed loop system that also contained multiple stages of broadband switching amplifiers in cascade, to demonstrate linearization viability. Greater than 20 dB of linearization was achieved on multi-carrier CDMA 2000 and WCDMA patterns, both at 874 MHz and 2.14 GHz.

  • The class-E/F family of ZVS switching amplifiers

    A new family of switching amplifiers, each member having some of the features of both class E and inverse F, is introduced. These class-E/F amplifiers have class-E features such as incorporation of the transistor parasitic capacitance into the circuit, exact truly switching time-domain solutions, and allowance for zero-voltage-switching operation. Additionally, some number of harmonics may be tuned in the fashion of inverse class F in order to achieve more desirable voltage and current waveforms for improved performance. Operational waveforms for several implementations are presented, and efficiency estimates are compared to class-E.

  • Input impedance of class E switching amplifiers

    This paper studies the effect of feedback capacitance on the input matching of a class E switching power amplifier. The on/off switching causes the input to see the feedback capacitance either amplified by the Miller effect or not and therefore, this feature is dependent on the gain of the amplifier. The time- varying feedback appears at the gate as negative input resistance, as a cause of severe second harmonic injection, and - if the supply voltage is varied to modulate amplifier gain as in envelope elimination and restoration (EER) - also as a cause for supply dependent input impedance. The paper discusses ways to minimize these effects.

  • Parallel operation of power transistors in switching amplifiers

    The previous literature has considered the equalization of collector currents of paralleled transistors in switching-mode power amplifiers by adding emitter resistors. This letter presents the possibility of equalizing the collector currents by using base resistors; the advantage is lower power dissipation. Experimental confirmation is given.
