ABSTRACT:
A high-voltage generating circuit suitable for a light receiving circuit includes a pulse oscillating circuit, a current drive circuit, a first capacitor, a second capacitor, a Cockcroft-Walton circuit, a low-pass filter. The pulse oscillating circuit produces a train of repetitive pulses. The current drive circuit produces a train of repetitive pulses which are in phase opposite to the train of repetitive pulses. The first capacitor couples the current drive circuit with the first input terminal of the Cockcroft-Walton circuit. The second capacitor couples the pulse oscillating circuit with the second input terminal of the Cockcroft-Walton circuit. The Cockcroft-Walton circuit boost the pulse voltage applied between the first and second inputs to produce a high direct current voltage. The low-pass filter removes the ripple components of the high direct current voltage. The Cockcroft-Walton circuit can be formed with a small number of circuit components.
