Abstract :
This paper presents a novel variable-gain single-bit ultra-wideband (UWB) quantizer suitable for baseband receiver front-end fabricated in 90 nm CMOS technology. The prototype chip is tested, and measurement results are provided. The proposed quantizer achieves a -3 dB bandwidth covering a spectrum from 10 MHz to 2.7 GHz. The overall gain can be varied from 23 dB to 33 dB while the noise figure (NF) is between 7 dB and 10 dB. The quantizer core occupies a die area of 0.25 × 0.17 mm2 and consumes 4.8 mW from a 1.2 V supply voltage.
