Abstract :
A three octave ultra-wideband 3-port circulator is proposed and implemented using 110 nm CMOS technology. The circulator operates across the frequency range from 0.5 to 4 GHz with supply voltage of 3 and - 3 V. The measured insertion loss is from 1.3 to 4.9 dB, return loss is better than 12 dB and isolation is more than 12 dB.
