| Abstract: | A new and compact scheme for a programmable current mirror is introduced. It features linear gain continuously adjustable in a wide range. In such a scheme differential pairs are used as current steering elements in order to provide gain programmability. All mirror transistors operate in strong inversion. Implementation of a linear OTA/multiplier is discussed. Experimental verification of the proposed scheme is provided. |
