  • High voltage shunt-regulator circuit with voltage-dependent resistor
    Patent number: 8552698
    Abstract: A voltage regulator circuit comprising a first circuit functioning as a voltage dependent resistor, the first circuit having an input coupled to a voltage source and an output and having a resistance dependent on the voltage applied across the circuit by the voltage source such that the resistance increases as the applied voltage increases; and a regulator coupled to the output of the first circuit for providing a regulated output voltage.
