A 1.4V signal swing hybrid CLS-opamp/ZCBC pipelined ADC using a 300mV output swing opamp

Scaling in CMOS technologies has made the application of traditional opamp topologies increasingly difficult. In the face of decreasing voltage headroom and intrinsic device gain, designers have employed techniques such as gain-boosting, correlated double sampling , and correlated level-shifting (CLS) [1] to maximize output swing for a given gain… (More)
