Abstract :
BiCMOS and CMOS versions of an operational transconductance amplifier (OTA) with an adjustable linear range that is independent of tail current are presented. The circuit is analysed based on the operation of transistors in weak and strong inversion and the analytical results are compared with the experimental data
