Abstract :
A novel CMOS low-voltage current feedback operational amplifier (CFOA) is presented. The proposed CFOA based on a new positive second-generation current conveyor (CCII+). The new circuit allows almost a rail-to-rail input and output operation; also, it reduces the offset voltage and provides high driving current capabilities. The CFOA is operating at supply voltages of plusmn0.75 V with a total standby current of 338 muA. The circuit exhibits better than 10 MHz bandwidth and plusmn1mA current drive capability. PSpice simulation results are given using 0.35mum technology for the proposed CFOA.
