Re-configurable receiver channels for a sensing device

A system and method for interference detection comprises coupling, in a first mode, an input of a first receiver channel with an input of a second receiver channel. In the first mode, the first receiver channel generates a first output signal by mixing a first portion of a combined resulting signal with a first mixing signal having a first phase. The combined resulting signal is simultaneously received from a first sensor electrode and a second sensor electrode. Further, in the first mode, the second receiver channel generates a second output signal by mixing a second portion of the combined resulting signal with a second mixing signal having a second phase orthogonal to the first phase. The first portion of the combined resulting signal differs from the second portion of the combined resulting signal.
