Abstrakt:	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 (∼57–500 MHz) without changing the feedback resistance. The FDCFOA has a standby current of 320 μA. Application of the proposed FDCFOA in realizing second order low-pass filter with controllable 3-dB bandwidth is given. PSpice simulations of the FDCFOA block and its application are given using 0.25 μm CMOS technology from MOSIS and dual supply voltages �0.75 V. [ABSTRACT FROM AUTHOR]
