    This paper describes a direct-conversion receiver for WiMedia UWB applications. The receiver consists of separate BG1 and BG3 LNAs including a 2.4-GHz notch filter, quadrature mixers, a base-band gm-C low-pass filter with variable gain, and a fast-hopping synthesizer. The UWB receiver is targeted for a mobile handset and therefore special emphasis has been placed on the reduction of interferers. The receiver achieves 60-dB gain, noise figure less than 6.2 dB, LO settling time of less than 3 ns and DC current consumption of 137 mA from a 1.2-V supply for BG1 operation mode. The chip was fabricated using 65-nm standard CMOS process.
