Voltage-Controlled Ring Oscillator for Low Phase Noise Application

  title={Voltage-Controlled Ring Oscillator for Low Phase Noise Application},
  author={Nisha Gupta},
A design for a voltage-controlled ring oscillator (VCO) is presented. The design allows an implementation of low frequency ring oscillator using relatively small devices and less stage. It is implemented using .18um technology provided by TSMC technology using 3.3V power supply. The VCO topology exhibits a very wide tuning range from few Hz to 368.9 MHz. It also features the rapid voltage swing and the 48% duty cycle with good transient characteristics which is difficult to get from the… CONTINUE READING
