Current generator for 6-bit active phase shifter

A current generator for a broadband 6-bit active phase shifter (PS) with low RMS phase error and low RMS gain error using 0.18 μm BiCMOS technology is presented. The ratio of two output currents of the current generator determines the phase shift. In the proposed current generator, the two output cu...
