ELECTRO-STATIC DISCHARGE FILTERING CIRCUIT AND METHOD, RESET CIRCUIT, AND ELECTRONIC DEVICE

摘要

This document discusses, among other things, an electro-static discharge (EDS) filtering circuit and method, a reset circuit, and an electronic device. The ESD filtering circuit comprises a first current dividing circuit and a second current dividing circuit which respectively share a current of a first power source signal and aggregate the shared currents to form a second power source signal upon filtering, wherein a voltage drop of the first current dividing circuit is constant and the second current dividing circuit is a pure resistor element circuit.

1. An electrostatic discharge (ESD) protection circuit, comprising:
a first input node; a first output node; a first shunt circuit, connected between the first input node and the first output node; and a second shunt circuit, connected between the first input node and the first output node, wherein the first shunt circuit is configured to conduct a current from the first input node to the first output node, and to block a current from the first output node to the first input node through the first shunt circuit, and wherein the second shunt circuit is configured to limit a magnitude of a current flowing through the second shunt circuit.
