An ESD protection circuit is provided having a first field-effect transistor, which has a first drain terminal, a first source terminal and a first control terminal, and having an input network which, in the event that a first voltage present between the first drain terminal and the first source terminal crosses a threshold value, alters a second voltage that appears between the first control terminal and the first source terminal. The input network contains a second field-effect transistor, complementary to the first field-effect transistor, having a second drain terminal, a second source terminal and a second control terminal, wherein the first drain terminal is connected to the second source terminal and, through a first resistance, to the second control terminal, and the second drain terminal is connected to the first control terminal and, through a second resistance, to the first source terminal.

ESD protection circuit for low voltages

An electrostatic discharge (ESD) protection structure is disclosed. The ESD protection structure includes an active device. The active device includes a plurality of drains. Each of the drains has a contact row and at least one body contact row. The at least one body contact row is located on the active device in a manner to reduce the amount of voltage required for triggering the ESD protection structure.
