Abstract
A clock generator circuit for producing a clock output having a controlled duty cycle is disclosed. A bi-stable circuit provides the clock output which is switchable to a first state in response to an edge of the input clock signal and to a second state in response to a feedback signal. A duty cycle detection circuit is configured to source a current to a node and to sink a current from the node depending upon the output clock state. A capacitor is connected to receive a duty cycle current relating to the current at the node, with a comparator circuit being configured to sense a voltage on the capacitor and to produce the feedback signal when the voltage is at a selected level.
