Abstract
The signal regeneration circuit recovers a digital signal from an input signal that is supplied via metallic isolation (galvanic separation). The circuit has two input terminals for the input signal and one output terminal for the recovered digital signal. A current direction sensor detects the current direction prevailing between the input terminals and outputs the signal in accordance with the last prevailing current direction. The circuit is advantageously used in connection with digital circuits that require potential isolation at their input terminals.
