Development of a 0.18-μm CMOS single-chip dual-band receiver for UWB applications

A new receiver front-end operating over the 3.1-4.8 and 6.3-7.9 GHz dual-band in the ultra-wideband (UWB) spectrum (3.1-10.6 GHz) was developed using a 0.18-μm CMOS process. The receiver front-end has a chip size of only 1.18 × 0.87 mm² and exhibits conversion gains of 12.5-16.5 dB and 14.5-16 dB over the 3.1-4.8 GHz and 6.3-7.9 GHz bands, respectively. The measured input 1-dB compression points are -4.1 and -5.2 dBm at 4 and 6.5 GHz, respectively. The measured noise figure is from 7.5 to 12.5 dB across 3.1-7.9 GHz and less than 10 dB up to 7 GHz. The receiver front-end consumes about 42 mA of current from a 1.8 V power supply.
