This paper presents a novel voltage follower, which is implemented in a 40nm CMOS process and under a supply of 1.1-V. In order to adapt to limited headroom, a low-threshold PMOS is used as the input transistor, and a novel low-voltage current source

A novel beat-frequency (BF) time quantizer with zero steady-state offset is proposed. The digital low-dropout (DLDO) regulator based on this quantizer can eliminate its inherent steady-state output error caused by the previous quantizer, thus improvi

This paper presents a CMOS buffer for near-rail voltage. Compared with conventional OTA-based structure, an additional super source follower is added in the loop, which hence maintains fairly high loop-gain even when the input voltage is very close t

This paper analyzes high linearity Cherry–Hopper programmable-gain-amplifier (PGA), which is a cascade of linear transconductance (Gm) stage and transimpedance (TIA) stage. Basing on these analysis, reasons for gain peaking of Gm–TIA PGA are disc
