Super-regenerative UWB impulse detector with synchronized quenching mechanism

This paper presents low power fully integrated super-regenerative UWB impulse detector with automatic adjustment of incoming pulses at highly sensitive region by using synchronized voltage controlled quenching mechanism. In-band and out-of-band interferences are eliminated by logic comparison and redundancy check between the outputs of multiple super-regenerators tuned within UWB spectrum. The test structure has been implemented on 0.18 mum CMOS technology, active area of 1.4 mm². The UWB signal to in-band interferer ratio of -36 dB is achieved with sensitivity of -95 dBm at data rate of 20 Mb/s and power consumption of 5 mW at 1.5 V.
