  • Band-stop noise modulated bandpass sigma-delta analog-to-digital converter

    In this paper, we present a method to reduce the effects of substrate noise on bandpass sigma-delta (SigmaDelta) ADCs through the use of band-stop noise modulation, where the notch of the modulation noise spectrum is centered around the input signal band. Several band-stop noise (BSN) resonator structures required for bandpass SigmaDelta ADC implementations are presented. The proposed designs have been adapted from traditional resonator designs. These include the forward Euler (FE) resonator, forward Euler non-delayed (FEND) resonator, lossless discrete integrator (LDI), and the double-delay resonator. An example utilizing a fourth-order BSN modulated bandpass SigmaDelta ADC with a 1-bit quantizer is presented. Additionally, a method to generate the required BSN sequence is proposed. Simulation results demonstrate that this architecture achieves a 7.7 dB improvement in SNR and a 19 dB improvement in SFDR over the traditional fourth-order bandpass SigmaDelta ADC

  • A SOI-CMOS micro-power first-order sigma-delta modulator

    The low-power and high-temperature potentials of SOI have been used to design a /spl Sigma//spl Delta/ modulator that achieves performances hard to obtain in bulk technology. From this first study, we estimate that further improvements based on the use of a technology with lower transistor size and lower threshold voltage, together with higher-order loop filters and higher OSR could boost the precision and further reduce the power dissipation, for the same signal bandwidth. The potential of FD SOI in high-temperature data conversion has also been demonstrated.

The input signal is encoded by a sigma-delta modulator, thus it eliminates the need for complicated analog-to-digital converters and requires no multipliers for any filter length. Computer simulations are included to confirm the convergence of the mean-squared error. Performances of the filter as adaptive noise canceller and adaptive line enhancer were also demonstrated by computer simulations.<<ETX>>

  • A frequency synthesizer realized by a transformer-based voltage-controlled oscillator for IEEE 802.11a/b/g channels

    A fractional-N frequency synthesizer for IEEE 802.11a/b/g standard with the design focused on voltage controlled oscillator (VCO) is proposed in this paper. Unlike the traditional approach of tuning VCO oscillation frequencies by capacitive varactors, the proposed VCO with a voltage-controlled inductor, which is made by an integrated transformer technology, is adopted. A digital delta-sigma modulator realized with FPGA verification is employed for fractional-N purpose to meet IEEE 802.11a/b/g channels. The frequency synthesizer is simulated in 0.18-mum CMOS process with a loop-bandwidth of 300 KHz for a 32-MHz reference and the power dissipation is about 40 mW from a 1.8-V supply

  • Analysis of non-uniform sampling effects in sigma-delta modulated signals

    The effects of non-uniform sampling in the /spl Sigma//spl Delta/-modulated DAC are discussed in this paper. The non-uniform sampling of the /spl Sigma//spl Delta/-modulated signals causes in-band noise in the DAC, which will be compared with the harmonic distortions in switched capacitor circuit and the that due to the signal-dependent nonlinearity in the 1-bit DAC. We describe an error-driven edge selection algorithm that suppresses the in-band noise and its implementation. We also propose a model of the in-band noise caused by the non-uniform sampling, which predicts the noise reduction of the spectral shaping in the frequency domain quantitatively based upon the transition probability of the modulator output.

  • A calibration-free 800MHz fractional-N digital PLL with embedded TDC

    An 800 MHz digital PLL with its TDC embedded within the DVCO is implemented in 65 nm CMOS and occupies 0.027 mm2. The design requires no calibration and achieves the fractional-N operation without a multi-modulus feedback divider. To further improve the TDC linearity, mismatch filtering is used to achieve a DNL of less than 3.5% of LSB.

  • A fourth-order cascaded sigma-delta modulator with DAC error cancellation technique

    An architecture that improves the performance degradation caused by the DAC nonlinearity in a cascaded multibit sigma-delta modulator is presented. The proposed architecture, with an extra feedback path in each internal stage, can totally cancel out the errors caused by the DAC nonlinearity at the final stage and, in general, increases the shaping function of DAC errors by one order for the other internal stages as compared to the MASH structure. Behavioral simulation shows that the proposed fourth-order modulator has excellent immunity of DAC nonlinearity over the MASH structure when OSR is greater than 16. With maximum DAC integral nonlinearity (INL) of /spl plusmn/0.05 LSB and an OSR of 32, an improvement of 15 dB over the MASH structure has been observed.

  • Dithering and its effects on sigma delta and multi-stage sigma delta modulation

    The spectrum of quantization noise in a dithered sigma-delta modulator and multistage sigma-delta modulator is derived under the constraint that the dithering signal does not cause overload. It is shown in the case of a simple sigma-delta modulation that no-overload dithering can smooth the noise spectrum and can make the binary quantization noise asymptotically uncorrelated with the input. It does not, however, make the noise white. In the case of multistage sigma-delta modulation with the appropriate dithering, the binary quantization noise becomes asymptotically white, even for a system with only two-stages. The signal-to-quantization-noise ratio is derived for sigma-delta and multistage sigma-delta oversampled analog-to-digital conversion with additive dithering. Simulation results are presented to support the theoretical analysis.<<ETX>>

  • Behavioral modeling and simulation of jitter and phase noise in fractional-N PLL frequency synthesizer

    A methodology is presented for predicting the phase noise and jitter of a fractional-N PLL based frequency synthesizer. Based on the phase/jitter properties extracted from transistor level through simulation, a voltage- domain behavioral model can give phase noise performance of fractional-N PLL frequency synthesizers in system level accurately, while the simulation efficiency is also improved by merging the VCO block operated at the highest frequency into those operated at lower frequency. Comparing to phase-domain simulation, the improved voltage-domain models do a better job of capturing the details of the behavior of the loop, details such as the signal capturing and escaping traces in fractional-N frequency synthesizer.
