摘要：A novel low-voltage CMOS current feedback operational amplifier (CFOA) is presented. This realization nearly allows rail-to-rail input/output operations. Also, it provides high driving current capabilities. The CFOA operates at supply voltages of with a total standby current of 304 . The circuit exhibits a bandwidth better than 120 MHz and a current drive capability of mA. An application of the CFOA to realize a new all-pass filter is given. PSpice simulation results using 0.25 CMOS technology parameters for the proposed CFOA and its application are given.
