Abstract:
An electrostatic discharge (ESD) protection circuit coupled with an input/output (I/O) pad is provided. The ESD protection circuit includes a first field oxide device coupled between a first terminal that is capable of providing a first supply voltage and the I/O pad. The first field oxide device includes a drain end having a first type of dopant and a source end having the first type of dopant. The first field oxide device includes a first doped region having a second type of dopant disposed adjacent to the drain end of the first field oxide device and a second doped region having the second type of dopant disposed adjacent to the source end of the first field oxide device.
