Abstract

This paper presents a low power and low cost front end for a direct conversion 2.5 GHz ISM band receiver composed of a 16 kV HBM ESD protected LNA, differential Gilbert-cell mixers, and high-pass filters for DC offset cancellation. The whole front-end is implemented in a 2P6M 0.18 mum RFCMOS process. It exhibits a voltage gain of 24dB and a SSB noise figure of 8.4 dB which make it suitable for most of the 2.5 GHz wireless short-range communication transceivers. The achieved power consumption is only 1.06 mW from a 1.2V power supply.
