Abstract
An input buffer insensitive to changes in supply voltage, temperature and other operational parameters comprises a decoupling capacitor and receives a reference voltage. In one embodiment, the input buffer comprises a CMOS invertor in which a PMOS transistor is provided to decouple the output signal from a fluctuation of the ground voltage ('ground bounce'). In one embodiment, a band gap type voltage regulator provides the reference voltage of the input buffer.
