Unique gate control concept for the open drain driver configuration

This paper proposes a unique gate control concept for an open drain driver configuration. The proposed concept uses pre-charged capacitor to control the gate of the driver by sensing the output node voltage. The concept provides the advantage of providing better control for the slope at the gate of the driver, which would then impact the output driver electrical performance of slew rate and duty cycle. The circuit has been designed in 130 nm using MOS transistors, resistors and capacitors.
