Abstract :
This paper presents the ultra-wide-bandpass super- regenerative filter of 1 GHz bandwith. The super-regenerative bandpass filter (SR-BPF) with synchronization loop is designed to extract UWB impulses. The DC-free on-off keying modulated data pattern is required to synchronize the filter response with high sensitivity. The super-regenerative bandpass filter, tuned at 7 GHz, is sensitive to -90 dBm signals of 1 GHz bandwidth. The test structure of SR-BPF has been implemented in 0.18 mum CMOS technology. The data exchange rate of 100Mb/s is achieved with power consumption of 3 mW at 1.5 V.
