Abstract :
This paper presents a CMOS fully differential current feedback operational amplifier with controllable 3-dB bandwidth. The FDCFOA has the advantage of a wide range controllable 3-dB bandwidth (~57 MHz to 500 MHz) without changing the feedback resistance. The FDCFOA has a standby current of 320 mu A. PSpice simulations of the FDCFOA block were given using 0.25 mum CMOS technology from AMI MOSIS and dual supply voltages plusmn0.75 V.
