AN HARMONIC METHOD FOR ANALYSING THE NONLINEARITIES OF INTEGRATED MOSFET TRANSCONDUCTIVE STRUCTURES

MOSFET 金属氧化物半导体场效应晶体管跨导结构是全集成 MOSFET-C连续时间滤波器的基本电阻结构.本文根据导出的 MOSFET 伏安特性的傅里叶公式,提出了失配情况下 MOSFET 跨导结构非线性的谐波分析法,并给出了详细表格以供应用时参考.

MOSFET transconductances are the basic resistive structures of MOSFET-C contin- uous-time,filters.In this paper,based on general MOSFET transconductive characteristics derived in Fourier series form,an harmonic analytic method is proposed and used in ana- lysing the nonlinearities of MOSFET transconductive structures,especially in mismatching cases.Also,some detail analytic results are given in a table for practical use.
