Abstract: A rail-to-rail input/output CMOS amplifier using common-gate compensation is proposed.The amplifier achieves a unity gain frequency of 25MHz while employing only one compensation capacitor.The power dissipation of the circuit is 1.34mW with a supply voltage of 5V and a biasing current of 20μA.Using the proposed circuit,a unity gain buffer is also implemented with a supply voltage of 3V and driving a capacitive load of 150pF.A THD of -51.6dB is obtained for a 2.66VPP 10kHz input sine signal.Simulated results reveal a high slew-rate and large driving capability.This amplifier is fabricated in CSMC 0.6μm CMOS mixed-signal technology.The test results are also provided.
