Abstract
A sensor device includes a high voltage circuit, a sensor and a charge storage. The sensor utilizes a low voltage supply. The high voltage circuit includes a blocking device and a regulating device. The blocking device is configured to block negative voltages of the high voltage supply. The regulated device is configured to receive a high voltage supply and generate the low voltage supply from the high voltage supply. The high voltage supply is DC. The charge storage has a vertical capacitor and is configured to maintain the low voltage supply during a power break and to store and maintain charge during non-break periods.
