Abstract
This paper describes 3.3 V silicon down conversion mixer with a current bleeding Gilbert multiplier and also compares the conventional current bleeding Gilbert mixer with an improved current bleeding circuit, detail analysis are given about the two circuits, using 0.35 um process. With a 1.675 GHz local oscillator (LO) and a 1.575 GHz RF input. The results show that the gain and IIP2 of the improved mixer is higher than conventional Gilbert-type mixer, while the noise figure is better.
