A 12-Bit Low-Input Capacitance SAR ADC With a Rail-to-Rail Comparator
IEEE Access, 2023 The input capacitance of the SAR ADC is considered a drawback in many applications. In this paper, a 12-bit low-power SAR ADC with low-input capacitance is proposed. The ADC is based on a separated DAC and sample-and-hold blocks (SB) structure.

Comparator with dynamic hysteresis
Electronics Letters, 1999 A comparator is presented which is based on the use of a time domain phenomenon called 'dynamic hysteresis'. This comparator features only one threshold and a short-time controllable noise immunity.

A low‐offset low‐power and high‐speed dynamic latch comparator with a preamplifier‐enhanced stage
IET Circuits, Devices and Systems, 2021 The preamplifier module is a crucial element while designing dynamic latch comparators. The traditional double tail comparator utilizes a differential pair as the preamplifier stage.

Advanced Healthcare Materials, EarlyView.This study presents an implantable, wireless, battery‐free oximeter that can continuously monitor physiologically consistent regional tissue oxygenation under dynamic changes of blood volume. This is achieved through multiwavelength photoplethysmography and validated both via Monte Carlo simulations and in vivo rat studies. Different stress events were
