Abstract :
Distortion of OTAs is caused by nonideal factors such as the mobility reduction effect, channel length medulation, transistor mismatch and so on. The transfer function of the proposed OTA is free from the mobility reduction effect. Thus, the proposed OTA is expected to have better linearity than conventional OTAs
