Zusammenfassung:A circuit for compensation of baseline voltage wander operating at an input of an isolator is disclosed. The circuit can compensate electronically the frequency response of an isolation circuit (e.g., a transformer) by increasing the pass band in the low frequency region in order to minimize the baseline wander caused by low inductance windings. The compensation circuit can be used to inject a current ramp proportional to the amplitude and the duration of the pulse and inversely proportional to the open circuit inductance of the isolation circuit.
