Abstract :
A new compact scheme for implementation of linear gain programmable current mirrors with wide range continuously adjustable gain is introduced. It is based on a balanced configuration of differential pairs used as current steering elements. All mirror transistors operate in saturated mode and in strong inversion. Applications of the mirrors for implementation of a linear OTA/multiplier with wide range gain adjustment range and constant input range are discussed. Experimental verification of the proposed scheme is provided.
