摘要

本文提出了一种基于ota的通用方形电路。所提出的平方器的重要特征是它有两个输入(电压输入vin和电流输入in)，它的输出可以是in v的平方或in的平方。通过在OTA输入端增加补偿电流来补偿由于输入电阻有限而导致的OTA中的非理想效应。利用PSpice软件进行了仿真，验证了电路的性能。

An OTA based versatile squarer circuit

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.
