Equations describing the high-frequency nonlinear behavior of common-emitter and differential-pair transconductance stages are derived. The equations show that transconductance stages using inductive degeneration are more linear than those using capacitive or resistive degeneration, and that the common-emitter transconductance stages are more linear than the differential-pair transconductance s...

Abstract— FinFet is evolved to overcome Moore's law limitations in nanometer regime. Transconductance circuit produces differential output currents, when differential input voltages are applied. A simple FinFet transconductance circuit structure modified from traditional MOSFET is proposed to preserve both area and power. The proposed design contributes a transconductance gain of 5.247 mA/v for...

–This paper presents a highly linear Operational Transconductance Amplifier (OTA) that combines two linearization techniques, one with adaptive biasing of differential pairs and second with resistive source degeneration. The Operational Transconductance Amplifier has ±0.9v power supply. Operational Transconductance Amplifier has been simulated with TANNER 0.18μm CMOS technology in Tspice. The s...

This paper presents the design of CMOS operational transconductance amplifiers (OTAs) with very small transconductance (of order of nano ampere per volt), which uses in very low frequency continuous time filters. This design uses current division technique to reduce the transconductance of OTA. This design is simulated in SPICE tool using 0.25μm technology model file.

In this paper we present an ultra low-voltage (ULV) floating-gate (FG) transconductance amplifier The amplifier can operate at supply voltages below 1V in a standard digital double poly CMOS process . The amplifier consists of a sinh shaped output current transconductance amplifier and a tanh shaped transconductance amplifier.

In this paper is presented a novel constant transconductance CMOS differential amplifier. The circuit uses a modified CMOS inverter to process polarisation currents of the complementary differential amplifier in order to maintain constant transconductance over the entire common-mode input voltage range. Simulation shows error less than ±6.12 % for a single supply voltage of 1.5 V. Key-Words: lo...

Current mode circuits cover an important area of application like filters, neural networks and analog-digital conversion. Current mode circuits, because of their special structure, need appropriate methodology during design process. This paper is an overview of most common problems related with analog and mixed digital-analog converters and filters performed in a CMOS technology. Laboratory mea...
