Abstract

This paper presents the monopulse comparator incorporating with the phase-invertible variable attenuator (PIVA). The sum and difference patterns are synthesized by combining two outputs of the attenuators after setting the transmission coefficients with the in-phase and out-of-phase shifting. The prototype is designed and fabricated by using CMOS 0.13-μm 1P8M technology. The prototype consumes 12mW from 1.2V. The measured results show that the gain of each signal-path is 4.88 dB at 24 GHz. The input P_ldB is -7 dBm and the sum/difference ratio is 25 dB.
