Realisation of Highly Precise and Low Power Tunable Voltage Amplifier Based on the Translinear Circuit Scheme of CCCII+

Abstract: In the past few years, advancements in the field of nano circuit design has become tougher than the demand. Low power devices have emerged tremendously.Both voltage mode aswell as current mode devices have proven alternative to each other for satisfying the demand of the growing market. As such, current conveyors have equitably established their uniqueness as an important circuit design element. The literature available to us during the few years in the field of analog VLSI design, quotes a huge number of application elements based on current conveyors. Likely, in this paper, a new tunable low power voltage amplifier based on the translinear circuit scheme of second generation current controlled current conveyor has been proposed. The modeling of the circuit presented in this paper employs the minimum number of passive elements. The magnitude of the tuning or the amplitude of the voltage presented here, is being controlled by means of two variable resistors. Current conveyor second generation translinear circuit scheme is taken into consideration to implement the proposed tunable voltage amplifier. CCCII works on the outlines of low power and low voltage design. Tunable voltage amplifiers find use in analog as well as in digital signal processing applications.
