In this work a dynamic biasing circuit for current conveyor (CCII) applications is proposed and discussed with circuitry details. This solution, applied for the first time to current-mode circuits, allows to decrease the steady state power consumption of the considered circuit, minimally affecting its performance. The dynamic biasing solution here conceived is able to sense the input signal providing an extra current to the CCII only when an input voltage variation occurs. The proposed conveyor shows a good transient response and allows to combine the needs of both low-power and high slew-rate characteristics that are mandatory in many practical applications and wireless systems. A case-study is also illustrated with simulation results.

Abstract

In this work a dynamic biasing circuit for current conveyor (CCII) applications is proposed and discussed with circuitry details. This solution, applied for the first time to current-mode circuits, allows to decrease the steady state power consumption of the considered circuit, minimally affecting its performance. The dynamic biasing solution here conceived is able to sense the input signal providing an extra current to the CCII only when an input voltage variation occurs. The proposed conveyor shows a good transient response and allows to combine the needs of both low-power and high slew-rate characteristics that are mandatory in many practical applications and wireless systems. A case-study is also illustrated with simulation results.
