Abstract :
In this paper, we propose a continuous-time differential single-bit quantizer intended for impulse radio ultrawideband (IR-UWB) receivers. It exploits an active balun at the input to obtain single-ended to differential conversion. The quantizer prototype was fabricated in 90 nm CMOS and occupies a chip area of 0.09 mm2. The proposed quantizer achieves a -3 dB bandwidth of 2.4 GHz with a high differential gain of approximately 35 dB and a sensitivity of 40 mV at 2 GHz. Power consumption is 13.1 mW from 1.2 V supply voltage and the performance was verified experimentally.
