Titel
A 780-nW Frequency-Agile Fully Integrated Super-Regenerative Multi-Channel UHF Receiver for Continuous Spectral Monitoring
Abstract
This paper proposes a frequency agile fully integrated super-regenerative receiver for spectral power estimation. A 180-nm implementation of the proposed receiver is presented with measurements. The receiver draws 26 mA from a 1.8 Volt supply to scan 60 frequency points between 380 and 960 MHz every 1.8 ms, hence 780 nW per channel. The ""resolution bandwidth"" lies between 2 and 15 MHz, depending on the quench-signal. No external filter components are used. Filter quality factors greater than 400 are achieved, using an on-chip inductor. The best measured receiver sensitivity is -75 dBm.
