    Abstract: The disclosed invention provides a structure and method for easily measuring capacitive and/or resistive components of a sensor system. In one embodiment, the structure comprises a signal generator configured to output a load current to a measurement element containing measurement sensor elements and a parasitic capacitance. A controllable excitation voltage is generated, via integration of the load current on the parasitic capacitance, and output to the measurement sensor elements having capacitive and resistive components. The controlled voltage through the measurement device may be manipulated to cause the capacitive and resistive components to exhibit a transient effect. The resulting output current, provided from the measurement device therefore has transient response characteristics (e.g., the settling time, amplitude) that can be selectively measured by a measurement circuit to easily determine values of the capacitive and resistive measurement elements. Furthermore, dedicated demodulation techniques may be used to measure the capacitive and resistive components.

    Abstract: A voltage controller for controlling an output voltage to a predetermined value. The voltage controller has a first terminal configured to connect a supply voltage, a second terminal configured to output the output voltage, a control voltage generating unit configured to provide a control voltage, and a control transistor. The control transistor is connected as a series controller between the first terminal and the second terminal. The control voltage can be applied to the control terminal of the control transistor, wherein the output voltage is controlled in a manner dependent on the supply voltage and the control voltage. Furthermore, an offset voltage is superposed on the control voltage.
