A 1.2V Inductorless Receiver Front-End for Multi-Standard Wireless Applications

Abstract — A novel, broadband, inductorless, multi-standard receiver front-end in a digital CMOS 90nm Low Power (LP) process is described. The front-end operates in the frequency range from 0.8 GHz up to 1.7 GHz. It achieves a voltage gain of 24dB and a noise figure of 5.5dB. The measured IIP3 and IIP2 of the receiver are –13dBm and +30dBm, respectively. The input return loss is better than – 10dB in the frequency band from 0.8 GHz up to 1.7 GHz. The front-end consumes 26mA from 1.2V power supply and occupies a chip area of 1mm2.
