Abstract
This paper proposes novel floating-gate MOSFET (FGMOS) based Voltage Buffer, Analog Inverter and Winner-Take-All (WTA) circuits. The proposed circuits have low power dissipation. All proposed circuits are simulated using SPICE in 180 nm CMOS technology with supply voltages of ±1.25 V. The simulation results demonstrate increase in input range for FGMOS based voltage buffer and analog inverter and maximum power dissipation of 0.5 mW, 1.9 mW and 0.429 mW for FGMOS based voltage buffer, analog inverter and WTA circuits, respectively. The proposed circuits are intended to find applications in low voltage, low power consumer electronics.
Highlights
Current trends in consumer electronics strive to achieve low-voltage and low-power circuit designs of voltage buffer, analog inverter and WTA having utility in portable electronics
It is capable of shifting the signal levels and incorporating tunable mechanisms due to its programmable threshold voltage. It operates normally below the operational limits of supply voltage levels for a particular technology and consumes less power than the minimum power required for a CMOS circuit of same technology without compromising on device performance [1]
Rail-to-rail input range is assumed and a supply voltage of ±1.25 V is taken for simulating both circuits
Summary
Current trends in consumer electronics strive to achieve low-voltage and low-power circuit designs of voltage buffer, analog inverter and WTA having utility in portable electronics. (2016) Design of Low-Voltage, Low-Power FGMOS Based Voltage Buffer, Analog Inverter and Winner-Take-All Analog Signal Processing Circuits. It is capable of shifting the signal levels and incorporating tunable mechanisms due to its programmable threshold voltage. It operates normally below the operational limits of supply voltage levels for a particular technology and consumes less power than the minimum power required for a CMOS circuit of same technology without compromising on device performance [1]. Exclusive features such as flexibility, controllability and tenability of FGMOS that yield better results in terms of power supply voltage motivated us to propose FGMOS based Voltage Buffer, Analog Inverter and WTA
