A Mode-I/Mode-III UWB LNA with programmable gain and 20 dB WLAN blocker rejection in 130nm CMOS

Wireless local area network (WLAN) transmissions in the 5–6 GHz band pose severe desensitization problems for UWB receivers. This paper describes a concurrent Mode-I (3.17–4.75 GHz) and Mode-III (6.34–7.92 GHz) UWB low-noise amplifier (LNA) employing a wideband filter with a tunable notch that attenuates WLAN blockers. Specifically, the notch attenuation and gain are tunable over a wide range. The gain is enhanced using wideband feedback and is programmable from 9–14.5 dB. Simultaneously, blocker attenuation of 10–20 dB over the WLAN frequency band is achieved. Implemented in a 0.13-µm CMOS process and operated with 4.8 mA bias current, the LNA achieves a NF of 4.3–5.1 dB and a minimum IIP3 of −1.1 dBm.
