A MOSFET active-disable switch is configured to clip an incoming signal in opposing directions when in an off state. By one approach the clipping is symmetrical and accordingly the switch clips both positive and negative peaks of the incoming signal. In many application settings it is useful for the clipping to serve to decrease a predetermined kind of resultant distortion such as even order distortion. In the on state this MOSFET active-disable switch is configured to not clip the incoming signal in opposing directions.

A signal conditioning circuit and a measurement device are provided. A selection circuit of the signal conditioning circuit outputs a first conduction signal when a voltage value of an input voltage signal is less than a threshold value of a voltage threshold signal, such that a first segmented voltage conditioning sub-circuit conditions, based on the received first conduction signal, the input voltage signal and outputs a first output voltage signal. The selection circuit outputs a second conduction signal when the voltage value of the input voltage signal is greater than the threshold value of the voltage threshold signal, such that the second segmented voltage conditioning sub-circuit conditions the input voltage signal and outputs a second output voltage signal.
