A Low-Voltage Floating-Gate MOS Biquad

Low Voltage Floating Gate MOS Transistor Based Four-Quadrant Multiplier

This paper presents a four-quadrant multiplier based on square-law characteristic of floating gate MOSFET (FGMOS) in saturation region. The proposed circuit uses square-difference identity and the differential voltage squarer proposed by Gupta et al. to implement the multiplication function. The proposed multiplier employs eight FGMOS transistors and two resistors only. The FGMOS implementation...

Ultra low-voltage floating-gate transconductance amplifier

The minimum supply voltage in low-voltage circuits can be defined as Vsup,min = 2(Vgs+Vsat) [1]. Low-voltage circuits are able to operate on a supply voltage of two stacked gate-source voltages and two saturation voltages. Differential amplifiers are biased with a transistor feeding a differential pair, where the current level is set by the bias transistor. The minimum input voltage in a NMOS i...

Low Voltage Squarer Using Floating Gate MOSFETs

A new low-voltage floating gate MOSFET (FGMOS) based squarer using square law characteristic of the FGMOS is proposed in this paper. The major advantages of the squarer are simplicity, rail-to-rail input dynamic range, low total harmonic distortion, and low power consumption. The proposed circuit is biased without body effect. The circuit is designed and simulated using SPICE in 0.25μm CMOS tec...

Tunable floating-gate low-voltage transconductor

This paper presents a 6 transistor fully differential dualended low-voltage (ULV) FGUVMOS operational transconductance amplifier (FGUVMOS-OTA), and a Gm-C filter where the FGUVMOS-OTA is used. The OTA has rail-torail operation. A basic Gm-C filter implemented with the OTA is presented. The cut-off frequency of the filter is tunable over almost 6 decades with a supply voltage below 1V.
