Study of RC-Diode ESD Protection Circuit for High-Frequency Applications

The RC-diode ESD protection circuit has been presented to offer the ESD protection in high-frequency integrated circuits. The protection circuit combines the ESD protection diodes with the embedded silicon-controlled rectifier (SCR) and the inserting resistors to provide the appropriate performances including ESD-current-handling ability, signal loss, and layout area. This work provides the thoroughly study of RC-diode ESD protection circuit in CMOS silicon chip.
