NEURON-MOS V-T CANCELLATION CIRCUIT AND ITS APPLICATION TO A LOW-POWER AND HIGH-SWING CASCODE CURRENT MIRROR

In this paper, a threshold voltage (V-T) cancellation circuit for neur on-MOS (nu MOS) analog circuits is described. By connecting the output terminal of this circuit with one of the input terminals of the nu MO S transistor, cancellation of V-T is realized. The circuit has advanta ges of ground-referenced output and is insensitive to the fluctuation of bias and supply voltages. Second-order effects. such as the channel length modulation effect, the mobility reduction effect and device mi smatch of the proposed circuit are analyzed in detail. Low-power and h igh swing nu MOS cascode current mirror is presented as an application . Performance of the proposed circuits is confirmed by HSPICE simulati on with MOSIS 2.0 mu p-well double-poly and double-metal CMOS device p arameters.
