Abstract

Utility of Schottky diodes fabricated in foundry digital 130-nm CMOS technology is demonstrated by implementing an ultra-wideband (UWB) amplitude modulation detector consisting of a low-noise amplifier (LNA), a Schottky diode rectifier, and a low-pass filter. The input and output matching of the detector is better than -10 dB from 0-10.3 GHz and 0-1.7 GHz, respectively, and almost covers the entire UWB frequency band (3.1-10.6 GHz). The measured peak conversion gain is -2.2dB. The sensitivity over the band for amplitude modulation with the minimum E _b/N_o of 6 dB is between -53 and -56 dBm. The power consumption is only 8.5 mW
