摘要: This article presents the optimal performance of a nonvolatile analogue memory cell fabricated in 1.2 µm CMOS process, which is programmed using LMS (least mean square) algorithm to implement an adaptive FIR filter used identify unknown signal. The store and update weight as charge floating gate pMOS transistor (FGMOS). Programming linear pulse density modulation scheme by means tunnelling hot injection electrons. behavior included programming method developed. performed very well, does not require signal be piecewise stationary, requires no manual operation other than selection step-size parameter.
