Integrated circuits with ESD protection devices
An integrated circuit with ESD protection comprises at least one ESD protection circuit block, which comprises a DC blocking capacitor connected in parallel with at least one compound semiconductor enhancement mode FET as an ESD protection device. The ESD protection circuit block that is built in an integrated circuit provides ESD protection while minimizing the generation of unwanted nonlinear signals resulting from the ESD protection. An integrated circuit comprises a high frequency circuit, a switching element, and two ESD protection circuit blocks, in which the high frequency circuit is connected between a first terminal and a second terminal for inputting or outputting the RF signals, the first ESD protection circuit block is connected from a branch node between the first terminal and the high frequency circuit to the switching element, and the second ESD protection circuit block is connected from the switching element to the ground.
