Abstract: 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.

Abstract: An integrated sensing device comprising a force sensor and fingerprint sensor disposed on different portions of a flexible circuit. The fingerprint sensor is disposed on a first portion of the flexible circuit and the force sensor is disposed on a second portion and the flexible circuit is configured such that the first portion is over the second portion. The force sensor comprises a compressible layer and one or more one force electrodes, where the compressible layer is disposed between the first and second portions.

Abstract: An example gate driver for an array of sensing pixels is disclosed. The gate driver includes a first flip-flop including a first data input and a first data output. The first data output is coupled to a first group of sensing pixels of the array. The gate driver also includes a second flip-flop including a second data input and a second data output. The second data output is coupled to a second group of sensing pixels of the array. The gate driver further includes a first insertion circuit configured to receive a first start signal and to cause, based on the first start signal, the second flip-flop to drive the second group of sensing pixels without the first flip-flop driving the first group of sensing pixels for a scan of the array.
