Abstract

This paper presents a novel pulsed wideband super-regenerative receiver (SRR). It features the combination of the super-regenerative oscillator with the injection locking oscillator to realize a compact and low power SRR receiver. This receiver allows to calibrating the frequency by injection locking thus suppressing the use of the power consuming PLL. It also benefits the low power characteristics by adopting the pulsed UWB signal working at 3.5-4.5 GHz. The proposed receiver is designed in the CMOS 0.18um technology with 1.2-V supply. This circuit consumes less than 6.6mA (excluding the digital part) for a 60-Mbps pulse rate, with a BER of 10^-4.
