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 0.9V voltage supply and 8μW power consumption, hence it is suitable for wearable electronics and biomedical applications. The simulation results obtained from the Cadence platform using 0.18μm TSMC CMOS technology show good performances for the designed circuit.
