Abstract
A MOS-type semiconductor clamping circuit is disclosed. The clamping circuit comprises a pmos device coupled to a nmos device in series to form the clamping circuit to selectively clamp a signal to a reference voltage, the signal configured to swing between a first voltage and a second voltage about the reference voltage. When the signal is swung between the first voltage and the second voltage, the pmos device and the nmos device are subjected to a voltage swing less than the voltage swing between the first voltage and the second voltage.
