A 1.2V Low Power CMOS Front End for Bluetooth

摘要

A 1.2 V Frontend intended for use in a Bluetooth receiver has been implemented in a 0.13um CMOS process. The Frontend comprises a LNA,I/Q mixer and a 1st order active LPF. The presented Frontend is highly integrated with only 7.2 mA current consumption with a 1.2 V supply. The Frontend achieves a voltage gain of 37 dB,7.55 dB SSB noise figure,-18.4 dBm IIP3 and input return loss of 8dB at 2.44 GHz. In this paper we present a direct and simple approach towards the LNA noise performance optimization.
