Abstract :
A CMOS ring-oscillator VCO with temperature compensation has been designed by using 0.6 μm CMOS technology. The proposed VCO has a wide operating range from 224 MHz to 974 MHz with a good linearity between the output frequency and the control input voltage. The operating frequency has a temperature coefficient of 86.3 ppm/°C in the 15~125°C range. The power consumption of this VCO is 8.3 mW
