发明名称 Mitigating side effects of impedance transformation circuits
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.
