چکیده
A single stage source coupled Complementary Metal Oxide Semiconductor Voltage Controlled Oscillator (CMOS VCO) is designed in this paper. The design is implemented in Cadence environment with high oscillation frequency and low power consumption. This design is a single stage and it has low phase noise because author has reduced noise sources. Oscillation frequency of the designed VCO is ranges from 1.052 GHz to 2.136 GHz. The circuit is simulated using 180nm UMC Technology. Simulation results are reported that the phase noise is -64.96dBc/Hz@1MHz and power consumption is 6.951 mW with 2.136 GHz oscillation frequency and 1.8 V supply voltage. Present results are compared with earlier published work and improvements are observed.
