Abstract

In this paper, we propose an ultra-wideband, differential, single-bit quantizer intended for impulse radio, ultra-wideband (IR-UWB) applications using standard 90 nm TSMC digital CMOS technology. The proposed quantizer is working in continuous-time for power-efficient IR-UWB implementations with a 5 GHz bandwidth and a very high differential gain of approximately 70 dB while consuming 33.5 mW from 1.2 V supply voltage. Coupled inductors are explored for bandwidth extension and post-layout simulated results are provided.
