Abstract
An electrostatic discharge (ESD) protection circuit includes an input terminal, a transistor, and an output terminal. The input terminal is configured to receive an input signal. The transistor includes a first source/drain region, a second source/drain region, and a drift region that has a resistance in series between the first and second source/drain regions and that is configured to attenuate an ESD voltage in the input signal. The output terminal is connected to the second source/drain region.
