Abstract
In this paper, a versatile squarer circuit based on OTAs is proposed. The important feature of the proposed squarer is that it has two inputs (voltage input vin and current input iin), and its output iout can be the square of in v or the square of iin. The non-ideal effect in OTAs caused from the finite input resistance is compensated by adding the compensation current at input of OTA. Simulation results by using PSpice are carried out to show performance of the circuit.
