摘要

本文提出了一种新的电流型平方电路。该设计基于mosfet的强反转非线性原理。针对短沟道mosfet中载流子迁移率降低所引起的二阶效应，提出了一种新的补偿技术。使用Tanner T-spice仿真工具验证了该设计在0.18μm CMOS工艺技术下的功能。仿真结果表明，最大线性误差为1.16%，功耗为331μW。

A new current-mode squaring circuit with compensation for error resulting from carrier mobility reduction

This paper presents a new current-mode squaring circuit. The design is based on MOSFETs translinear principle in strong inversion. A new compensation techniques to minimize the second order effects caused by carrier mobility reduction in short channel MOSFETs is proposed. Tanner T-spice simulation tool is used to confirm the functionality of the proposed design in 0.18μm CMOS process technology. Simulation results indicate that the maximum linearity error is 1.16 % and the power consumption is 331μW.
