    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.

    Abstract: A device for converting analog to digital is disclosed. The device includes a dual mode converter and a control unit. The dual mode converter has a coarse mode and a fine mode. The dual mode converter is configured to receive an input signal and convert the input signal to a digital output having a selected resolution. The control unit is coupled to the dual mode converter and is configured to operate the converter in the coarse mode until a coarse approximation is obtained and to operate the converter in the fine mode until a fine approximation is obtained having the selected resolution. The fine mode includes multi-bit incremental tracking.
