Abstract: In a signal potential converter, a capacitor receives an input signal CIN at one terminal thereof and has the other terminal thereof connected to a terminal node. A clamp circuit defines a potential (signal IN) at the terminal node within the range of a first potential to a second potential. The clamp circuit includes a level adjuster circuit configured to adjust at least one of the first and second potentials according to a supply voltage of a circuit that drives the input signal CIN.

Abstract: Disclosed herein is a signal potential converter which may perform high-speed operation and which may still maintain intended signal amplitude and operate normally even while operating at a low rate or receiving a burst signal. In this signal potential converter, a capacitor receives an input signal CIN at one terminal thereof and has the other terminal thereof connected to a terminal node. A clamp circuit defines a potential at the terminal node, i.e., a signal IN, within the range of a first potential to a second potential. If a potential at the terminal node is higher than a third potential, a voltage holder circuit operates to raise the potential at the terminal node. If the potential at the terminal node is lower than the third potential, the voltage holder circuit operates to lower the potential at the terminal node.
