Abstract
An apparatus is disclosed that includes a voltage-controlled delay generator. In an example aspect, the apparatus includes voltage-controlled timing circuitry, duty cycle detection circuitry, and output circuitry. The voltage-controlled timing circuitry is configured to receive a control voltage. The voltage-controlled timing circuitry includes a current source, a control transistor, and a capacitor that are configured to produce a voltage indicator based on the control voltage. The duty cycle detection circuitry is coupled to the voltage-controlled timing circuitry. The duty cycle detection circuitry is configured to detect the voltage indicator and provide a duty cycle indicator based on the voltage indicator. The output circuitry is coupled to the duty cycle detection circuitry and is configured to generate a duty signal based on the duty cycle indicator.
