ABSTRACT:
Method and apparatus for adjusting an impedance of a substrate of a Metal-Oxide-Semiconductor (MOS) transistor by providing a bias voltage and connecting a frequency-selective circuit between the substrate and the bias voltage. The frequency-selective circuit is also provided with at least one reactive element, such as an inductive element or a capacitive element, to obtain a certain frequency-response of the frequency-selective circuit and thus adjusts the substrate impedance of the MOS transistor. The method and apparatus are compatible with standard CMOS technology and applicable to RF switches, including T/R switches for processing high-frequency analog signals.
