Abstract :
A 1.0GHz, Voltage Controlled Oscillator (VCO) fabricated in TSMC 1.2V 1P9M 65nm CMOS LP-Process is presented in the paper. The output frequency is proportional to the control voltage (Vctrl). The advantage of the architecture is very simple and easy to be realized and it aims at low power, low area and low cost. Measured results show that the VCO operates at 400 MHz to 1.6 GHz while Vctl ranges from 0.8V to 1.4V and the tuning range is even larger than 100%. The VCO works well in Register File and consumes 0.5 mA from a 1.2-V power supply, and occupies an area of 400 μm2.
