DRIVER CIRCUIT CHARGING CHARGE NODE

摘要

Disclosed is a driver circuit. The driver circuit includes a clamp transistor, a comparison voltage transistor, an amplification transistor, a bias transistor, and a charge circuit. The comparison voltage is configured to provide a comparison voltage. The amplification transistor includes an amplification gate connected to a first node of the clamp transistor, a first amplification node configured to receive the comparison voltage, and a second amplification node connected to a gate of the clamp transistor. The bias transistor is configured to supply a bias voltage. The charge circuit is at least one of configured to drain a current from the first node through the clamp transistor and configured to supply a current to the first node through the clamp transistor.
