Abstract
A voltage mode operational amplifier (op amp) built from two current conveyors is proposed as an approach to an op amp featuring a high slew rate. The suggested configuration has the slew rate characteristics of commonly available transimpedance amplifiers but provides two high impedance (voltage mode) inputs similar to conventional op amps. The configuration has been verified experimentally by using a dual current feedback op amp in a noninverting amplifier connection. From the measured results it is concluded that the proposed configuration is suited for the implementation of high speed integrated op amps in either bipolar or CMOS technology.
