Abstract
The present invention relates to an electrostatic discharge (ESD) protection circuit, and more particularly to a low parasitic capacitance electrostatic discharge protection circuit. An ESD protection circuit is established with the structure in accordance with the present invention comprising a plurality of discharging paths. The ESD protection circuit is connected to the input/output pad of a radio frequency (RF) core circuit. Such that, the RF core circuit with the ESD protection circuit of the present invention feature much higher ESD robustness. And the parasitic capacitance of the ESD protection is reduced because of the structure of the present invention.
