Abstract
A pre-driver includes a first inverter, a second inverter, an amplifier, a first capacitor, and a second capacitor. The first inverter has an input terminal for receiving an input signal at an input node, and an output terminal coupled to an inner node. The second inverter has an input terminal coupled to the inner node, and an output terminal for outputting an output signal at an output node. The amplifier is configured to amplify the input signal by a gain factor so as to generate an amplified signal and an inverted amplified signal. The first capacitor has a first terminal coupled to the output node, and a second terminal for receiving the amplified signal. The second capacitor has a first terminal coupled to the inner node, and a second terminal for receiving the inverted amplified signal.
