A compact coupled source followers (CSFs)-based low-pass filter (LPF) topology is presented with excellent power efficiency and high linearity. It synthesizes a 3rd-order low-pass transfer function in a single stage that is comprised of two CSFs and

Low-noise ring amplifiers required for high-precision analog–digital converters (ADCs) greater than 16 b remain unexplored. This article demonstrates a two-step successive approximation (SAR) ADC achieving 91-dB signal-to-noise-and-distortion-ratio

The two-step SAR architecture has been a popular choice for power-efficient ADCs used in applications such as medical imaging. The simple and scalable architecture of the SAR ADC enables efficient multi-bit conversion per stage [1, 2] however, the ma

A practical model for characterizing comparator metastability errors in SAR ADCs is presented, and is used to analyze not only the conventional SAR but also LSB-first and asynchronous versions. This work makes three main contributions: first, it is s

In this paper, passive compensation techniques are proposed: to improve the settling performance of a ring amplifier and to minimize the power consumption of ring amplifiers in high speed applications. The ring amplifier is an efficient solution for

Ring amplifiers have emerged as a scalable amplification technique. This work is a ring amplifier built with current-starved inverters in the intermediate stage. This structure allows for the implementation of a dynamic deadzone that allows a single

A reference-free stochastic ADC is proposed by utilizing both spatial averaging and oversampling noise-shaping schemes. By implementing multiple VCO-based quantizers in parallel, stochastic spatial averaging for quantization errors is inherently obta

This paper proposes a spatial averaging stochastic oversampling ADC. By implementing VCO-based quantizers in parallel, the stochastic spatial averaging is inherently obtained along with 1st-order noise shaping. In an open-loop oversampling configurat
