Abstract
There are unique benefits to current conveyor ICs in applications from LF to RF. A precision rectifier needing only two resistors and two diodes is just one example from many. This and various other applications are explored by this chapter. The chapter also shows a close relative, another sort of transconductance amplifier but with a difference. Here, with a unity gain buffer at the output, one would have a current feedback op-amp (CFBO);however, the buffer is missing so that the device has a very high impedance (current source) output just like an operational transconductance amplifiers (OTA). But instead of inverting and non-inverting (I and NI) inputs both of high impedance, this device known as a current conveyor (CC) has a high impedance NI input and a low impedance I input, just like a CFBO. This chapter also describes a simplified representation of a CC, the relation between the terminal currents and voltages, and the pin-out of the CCII01 device.
