Abstract
A voltage-controlled ring oscillator (VCRO) and a VCRO-based sigma delta modulator having capability of enabling and disabling the VCRO cells. A VCRO includes a plurality of inverters coupled in a ring and a transition detector. The transition detector detects a transition of a first inverter and sends a control signal to enable a second inverter if the transition of the first inverter is detected. The transition detector may include a comparator configured to compare an input and an output of an inverter(s) to detect the transition of the first inverter and a latch configured to hold the control signal until it is reset.
