Virtual ground reference buffer technique in switched-capacitor circuits
The performance of switched-capacitor circuits depends highly on the op-amp specifications. In conventional designs, trade-offs in speed, noise, and settling accuracy make it difficult to implement power-efficient switched-capacitor circuits. The problem originates from the inverse relationship …

A comparator-based switched-capacitor pipelined analog-to-digital converter
A new comparator-based switched-capacitor(CBSC) technique is proposed that eliminates the need for high gain op-amps in switched-capacitor circuits. The CBSC technique replaces the op-amp in switched-capacitor circuits with a comparator and a current source. Compared to op-amps, comparators suffer …

A comparative study of high voltage analog switch topologies
… gain feedback amplifiers, sample and hold circuits, and other switched capacitor circuits. In this document, four high voltage analog instrumentation switches were designed using different topologies. The four switches were then compared with respect to various important switch performance …

A zero-crossing switched-capacitor filter design
Design of switched capacitor circuits in scaled CMOS technologies is becoming difficult because of low device intrinsic gain and reduced power supply voltage. To solve these problems, comparator-based switched-capacitor (CBSC) circuits and zero-crossing based circuits (ZCBC) were suggested as a …

Circuits and algorithms for pipelined ADCs in scaled CMOS technologies
… high-gain feedback loops traditionally used in switched capacitor circuits. This research involves two complementary methods for addressing scaling issues. First is the development of two blind digital calibration techniques. Decision Boundary Gap Estimation (DBGE) removes static non-linearities …

Reconfigurable and Interference-Tolerant Receivers for Next Generation Wireless Systems
… adopted in modern receiver architectures, these switched-capacitor circuits remain inherently vulnerable to blockers at clock harmonics, due to their hard-switching nature. These blockers, common in 5G bands, pose a key bottleneck, delaying the realization of fully integrated multi-band, …
