Abstract: A common mode noise sensor with a single amplification path is disclosed. The common mode noise sensor includes first and second terminals for receiving respective first and second signals from a power supply, an amplifier stage connected to the first and second terminals and having an output and a resistor network connected to the amplifier stage. The resistor network is arranged such that the output of the amplifier stage is configured to provide an output signal in which a differential mode noise in the first and second signals is suppressed in preference to a common mode noise in the first and second signals.
