Abstract

This paper presents simulation results of an active down-conversion Mixer used in a frequency-hopped spread-spectrum receiver operating in the 863-870 MHz European band for wireless sensor applications. The doubly-balanced Mixer is designed using the Gilbert cell with the current-reuse bleeding technique based on the 0.35-mum technology. The various parameters of the Mixer, as noise figure, conversion gain and linearity are simulated and optimized to meet Mixer specifications. The Mixer simulations show 12.5 dB conversion gain, -10.25 dBm CP-_1dB, and 9.74 dB NF.
