A novel 4-quadrant analog multiplier using Floating Gate MOS (FGMOS) transistors operating in saturation region are implemented. Floating gate MOSFETs are being utilized in a number of new and existing analog applications. These devices are not only useful for designing memory elements but also we can implement circuit elements. The main advantage in FGMOS is that the drain current is proportio...

in this paper, a low voltage and low power (lv/lp) operational transconductance amplifier (ota) using fgmos (floating-gate mos) transistor is proposed. the relative tuning range of 50 is achieved in this ota while only consumes 40 µw with 1.0 v supply voltage in tsmc 0.18 µm cmos technology. the simulation results of the proposed ota show an open loop gain of 30.2 db and a unity gain frequency ...

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...

We extend a class of analog CMOS circuits that can be used to perform many analog computational tasks. The circuits utilize MOSFET’s in their subthreshold region as well as capacitors and switches to produce the computations. We show a few basic currentmode building blocks that perform squaring, square root, and multiplication/division which should be sufficient to gain understanding of how to ...

Low voltage non-linear computational circuits useful for analog VLSI signal processing applications based on floating gate MOS transistors (FGMOSFETs) are presented. The FGMOS transistors operate in the saturation region. The variable equivalent threshold voltage (VT) of the FGMOS transistor is exploited in such a way to transform it to a simple MOSFET of zero VT. A bias circuit using a convent...

We present the negativeand positive-feedback circuit congurations of continuous-time oating-gate MOS circuits. We start by reviewing the dynamics of our pFET and nFET single-transistor synapses. We present the range of possible stabilizing and destabilizing types of feedback in circuits with one oating-gate synapse, including data from nFET and pFET synapses. We then show examples of competitiv...

Abstract-Low-voltage and low-power circuit structures are substantive for almost all mobile electronic gadgets which generally have mixed mode circuit structures embedded with analog sub-sections. Using the reconfigurable logic of multiinput floating gate MOSFETs, 4-bit full adder has been designed for 1.8V operation. Multi-input floating gate (MIFG) transistors have been anticipating in realiz...

We describe a family of current-mode circuits with multiple inputs and multiple outputs whose output currents are products and/or quotients of powers of the input currents. These circuits are made up of multiple-input oating-gate MOS (FGMOS) transistors operating in the subthreshold regime. The powers are set by capacitor ratios; hence, they can be quite accurate. We analyze the general family ...
