A Low Power Ku Phase Locked Oscillator in Low Cost 130nm CMOS Technology

摘要

This paper reports on a Ku-band low-power integer N phase locked oscillator designed to investigate the potentialities of a low-cost 130nm CMOS technology for videobroadcasting and radiometryapplications. The design and the characterization of the prototype are described and the main performances are\udreported and compared to literature. The PLO generates an output tone in the 14.2GHz–15.1GHz frequency range. The phase noise is 68.9dBc/Hz for an offset frequency of 100kHz from a 15GHz carrier, and can be enhanced of about 20dB. The circuit core sinks 23.7mA from 1.2V supply.
