Abstract
The invention provides a signal coupling circuit and method for coupling an analog input signal to a processing circuit. The signal coupling circuit includes a number of first coupling units, a second coupling unit and a first multiplexer. The first coupling units are coupled to a first input terminal of the processing circuit, for respectively receiving a plurality of input signals. The first multiplexer is coupled between the first coupling units and the processing circuit for selecting one of the input signals and transmitting the selected input signal to the processing circuit. The second coupling unit is coupled to a second input terminal of the processing circuit, for receiving a common reference signal, wherein the processing circuit uses the common reference signal as reference for processing some or all of the input signals.
