Abstract

This paper presents a voltage-mode low-voltage low-power diode-less rectifier with only one active element, the fully differential difference transconductance amplifier (FDDTA). The multiple-input floating-gate MOS (FG-MOS) transistor is used to build the differential pairs of the FDDTA resulting in the reduced count of transistors, circuit simplicity and the capability to work under low-voltage supply with extended input voltage range. The rectifier was designed with 0.9[Formula: see text]V voltage supply and 8[Formula: see text][Formula: see text]W power consumption, hence it is suitable for wearable electronics and biomedical applications. The simulation results obtained from the Cadence platform using 0.18[Formula: see text][Formula: see text]m TSMC CMOS technology show good performances for the designed circuit.
