Low-voltage diode-less rectifier based on fully differential difference transconductance amplifier

journal article in Web of Science

English

This letter 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 transistor (FG-MOS) is used to build the differential pairs of the FDDTA resulting in 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 V voltage supply and 8 uW of power consumption hence it is suitable for wearable electronics and biomedical applications. The simulation results obtained from the Cadence platform using 0.18 um TSMC CMOS technology show good performances for the designed circuit.
