Abstract
A low-power PMOS Colpitts voltage controlled oscillator (VCO) topology using the technique of gate inductive feedback is demonstrated. The topology enhances the negative conductance and overcomes the start-up difficulty of the conventional Colpitts VCO. This enables the Colpitts VCO to be operated in low-power consumption. The fabricated VCO operates from 7.4 to 7.9 GHz with 7% tuning range, a power consumption of 4.9 mW, and a supply voltage of 1.5 V. The measured phase noise at 1 MHz offset is 108.3 dBc/Hz at 7.9 GHz.
