Design of Gilbert Cell mixer in 0.18 μm CMOS technology and IF filter for FM receiver

摘要

This paper describes a doubly balanced Gilbert Cell mixer designed in CMOS technology. A 100 mV input signal was applied at both RF and LO port at different frequencies and their simulation curves were studied, the output voltage is approximately 300 mV. Gilbert cell mixer was designed till to the layout. For the IF filter, passive elements were studied.
