Patent Primary Examiner
An electrostatic protection circuit connected with an internal circuit is provided. The electrostatic protection circuit includes: a first circuit, a first diode connected in parallel with the first circuit, a second circuit, and a second diode connected in parallel with the second circuit. The first circuit is connected between a power supply pad and an internal circuit input terminal. The second circuit is connected between the internal circuit input terminal and a ground pad. The first circuit and the second circuit are diode-triggered silicon controlled rectifier circuits. The technical solution of the disclosure can improve electrostatic protection capability of a charged device model of a chip.
