A new low voltage operational transresistance amplifier and its applications in analog circuit design

In this paper, a low voltage Operational Transresistance Amplifier with class-AB output stage is proposed. The usefulness of the amplifier is illustrated by providing its applications in variable gain amplifier, biquad and oscillator design. The circuits are suitable for low voltage operation and operate with a single 0.5 V power supply. In order to show the usefulness of the proposed circuits, detailed simulation results with Spectre in Cadence Design environment are obtained.
