Abstract
A voltage clamp circuit for reflecting a voltage at an input node includes a circuit for providing at least two currents at its output terminal, and at least two diodes each being connected to an output terminal of the circuit for providing at least two currents. The diodes also are connected to a line of a ground voltage and to the input node respectively. The circuit includes an alternative current path connected to an output terminal of the circuit for providing at least two currents and to a current sinking node. The voltage at the input node thus is reflected as the voltage between two output nodes when the voltage at the input node is lower than a clamping voltage and so that the voltage is fixed between the two output nodes to the clamping voltage when the voltage at the input node is higher than the clamping voltage.
