Abstract
Commercially available discrete current mirrors are used to realize a differential current electronically-variable phase-shifter, capable of operating at high frequencies. The phase-shift is controlled by varying the bias currents, which change the input resistances of the current mirrors, resulting in corresponding changes in the phase angles of the differential currents. The present phase-shifter is also readily cascadable. Experimental results are given and some applications are discussed. © 1988 Taylor and Francis Group, LLC.
