This paper describes a doubly balanced Gilbert Cell mixer designed in BJT and CMOS technology to operate within 0 to 5 V. A 100 mv input signal was applied at both RF and LO port at different frequencies and their simulation curves were studied for a multiplier. The design done in BJT was taped out for fabrication and the chip on its return from foundry, was tested for its results. A comparison...

This paper presents a CMOS rectifier for RF energy harvesting. The structure of the proposed design is based on modified cross-coupled architecture. It employs an adaptive body biasing technique to lower transistor threshold voltage (V th ) when PMOS ON. would increase conduction current. Moreov...
