Abstract
An apparatus and method for synchronously discharging multiple capacitive loads. In one embodiment, the apparatus includes first and second discharge circuits for discharging first and second capacitive loads, respectively. The apparatus also includes a control circuit coupled to the first and second discharge circuits and configured to control the second discharge circuit. The control circuit includes a first scaler circuit configured to generate a first scaled voltage based on a first voltage on the first capacitive load, a second scaler circuit configured to generate a second scaled voltage based on a second voltage on the second capacitive load, and a comparator circuit for comparing the first and second scaled voltages. The comparator circuit asserts a control signal when the second scaled voltage exceeds the first scaled voltage. The second discharge circuit discharges the second capacitive load when the comparator circuit asserts its control signal.
