About this document
Digitally Controlled Ring Oscillator Design by Vinidhra Shivakumar is a document available to read on EtoBox.
The document describes a digitally controlled oscillator (DCO) circuit designed for RF applications. The DCO uses a ring oscillator topology with tristate inverters as delay cells. The frequency of oscillation can be digitally tuned by varying the driving current through the use of 8 control bits, allowing different widths of transistors in parallel rings to control the delay. Spice simulations and equations are provided to analyze the circuit operation and tuning characteristics.
