A Two-Stage Fully Differential Inverter-Based Self-Biased CMOS Amplifier With High Efficiency

TL;DR: A two-stage fully differential CMOS amplifier comprising inverters as input structures and employing self-biasing techniques is presented, which achieves the highest efficiency of its class and although it relies on a quasi-class-A topology, it is comparable to class-AB amplifiers.
Journal ArticleDOI

Systematic design for optimization of high-speed self-calibrated pipelined A/D converters

TL;DR: In this paper, a multibit, rather than single-bit resolution per-stage architectures have been considered for optimizing the resulting area and power dissipation while minimizing stringent requirements of the constituting building blocks.
Proceedings ArticleDOI

Two-stage fully-differential inverter-based self-biased CMOS amplifier with high efficiency

TL;DR: A novel two-stage fully-differential CMOS amplifier comprising two self-biased inverter stages, with optimum compensation and high efficiency, shown that it achieves the highest efficiency of its class and comparable to the best class AB amplifiers.

A 0.9V /spl Delta//spl Sigma/ Modulator with 80dB SNDR and 83dB DR Using a Single-Phase Technique

TL;DR: A 2nd-order DeltaSigma ADC implemented in 0.18mum CMOS achieves 80dB SNDR and 83dB DR over a 10kHz BW employing a single-phase technique to reach such performance.
Proceedings ArticleDOI

An improved low-voltage low-power CMOS comparator to be used in high-speed pipeline ADCs

TL;DR: Simulated results of the proposed circuit in a 0.35 /spl mu/m standard CMOS technology operating at supply voltages within the range of 1.0-1.5 V show that this comparator achieves low offset, reduced kickback noise, high mean-time to failure and exhibits low-power dissipation at very high-speed operation.
