This paper gives a brief overview of voltage controlled oscillator(VCO) based on Si CMOS and SiGeBiCMOS process technologies. The status of designing techniques for high performance VCO is summarized because of its importance for high-speed communication systems and radar sensors. Then, the development tendency of VCO is introduced.
In this paper, an ultra-low-power baseband processor for a UHF Passive RFID Tag is presented. It proposes a prominent RFID tag baseband architecture which is compliant with the ISO18000-6B UHF RFID protocol. Several low-power design approaches are employed to reduce the power consumption, including low voltage low operation frequency approach, clock gating technique, clock strobe design, asynchronous...
