Design of Ultra Wideband oscillator in 0.18 μm standard CMOS technology

This paper describes the design of a 3-5 GHz oscillator for Impulse-Radio Ultra-Wideband (IR-UWB) transceiver in the 0.18 μm CMOS technology. The most important specifications for the voltage control oscillator (VCO) are provided and architecture for an existing frequency plan is introduced along with a discussion on its performance and implementation. The simulated VCO can achieve very wide tuning range along with low phase noise performance that varies from -92.02 dBc/Hz to -73 dBc/Hz at 1 MHz frequency offset from the carrier and the overall power consumption is 18.1 mW from a 1.8V voltage supply.
