Abstract :
This paper describes how the translinear (TL) principle can be purposefully exploited for MOS transistors operating in subthreshold region. Due to the exponential current-voltage relationship of subthreshold MOS transistors, they are comparable with BJTs as far as TL principle is concerned. Here squaring and square rooting circuits are implemented using subthreshold MOS devices.
