Design of a low-power low-phase noise MEMS compatible S-band oscillator in 130 nm CMOS technology

This paper discusses the design details of a MEMS compatible low-power, low-phase noise CMOS oscillator. The VCO was designed in UMC 130 nm RFCMOS technology for a multiband system with low power dissipation of 1.17 mW and low phase noise of -117.78 dBc/Hz at 1 MHz offset from the oscillation frequency. The centre frequency of oscillation was chosen to be 2.4 GHz which is a standard for Zigbee applications.
