Current feedback amplifiers (CFAs) provide fast response and high slew rate with Class-AB operation. Fast response, low-dropout regulators (LDRs) are critical for supply regulation of deep-submicron analog baseband and RF system-on-chip designs. An LDR with an CFA-based second stage driving the regulation field-effect transistor is presented. The low(More)
Low-noise, low-dropout (LN-LDO) regulators are critical for supply regulation of deep-submicron analog baseband and RF system-on-chip designs. A low 1/f noise LDO regulator utilizing a chopper stabilized error amplifier is presented. In order to achieve fast response during load transients, a current-mode feedback amplifier (CFA) with an asymmetrical input(More)
