Body-triggered ESD protection circuit |
摘要 |
A protection circuit is designed with an external terminal (300), a reference terminal (126) and a substrate (342). A semiconductor body (338) is formed by an isolation region (332, 340) formed between the substrate and the semiconductor body, thereby enclosing the semiconductor body. A plurality of transistors is formed in the semiconductor body. Each transistor has a respective control terminal (354) connected to a common control terminal (321) and a respective current path connected between the external terminal and the reference terminal. A capacitor (314) is connected between the semiconductor body and the external terminal. A resistor (318) is connected between the semiconductor body and the reference terminal.
