Nanowatt-power-level automatic-switch circuit combining CMOS and photodiode

Abstract

A nanowatt-power-level automatic-switch circuit that combines an ultralow-power CMOS level converter and a photodiode has been developed as a sensor application. The level converter is a single-input latch-type circuit featuring the use of a depletion-type common-gate MOSFET as a driver transistor, no DC current path, and nanowatt-order power dissipation… (More)
