Abstract
The disclosure relates in some aspects to electrostatic discharge (ESD) protection for an electronic circuit. In some aspects, the ESD protection includes a buffer circuit that increases the slew rate of a signal that controls a discharge circuit. In some aspects, the ESD protection includes a voltage-dependent resistance circuit that adjusts a time constant of a resistive-capacitive filter based on a voltage on a supply node.
