摘要： Implementations to mitigating side effects of impedance transformation circuits are described. In particular, mitigation circuitry may be coupled to a high impedance circuit to minimize or eliminate non-linear output of the high impedance circuit in order to provide a well-defined bias voltage to the input of a buffer or amplifier device coupled to a capacitive sensor. Additionally, the mitigation circuitry may be coupled to the high impedance circuit to reduce or eliminate rectifying effects of the high impedance circuit. Accordingly, a bias voltage can be utilized to provide a stable operating point of the buffer or amplifier device via a high impedance circuit utilizing one or more impedance transformations.

摘要： A circuit arrangement for voltage regulation comprises an output, a controllable output transistor connected to the output, an error detection circuit, and a monitoring control circuit. A voltage-regulated output potential can be tapped off the output, the controllable output transistor is connected to the output on a load side and the output transistor comprises a control terminal. The error detection circuit provides a regulating signal if a deviation between the output potential or a potential derived from the output potential and a desired value occurs. By means of the regulating signal the control terminal can be charged or discharged dependent on the deviation and the monitoring control circuit monitors the regulating signal and performs, if the regulating signal lies outside a predetermined range, an additional charging or discharging of the control terminal until the regulating signal lies within the predetermined range.
