Abstract: Embodiments of the present invention are directed to processing an incoming signal by using a demodulation signal, while controlling the phase of the demodulation signal in relation to the incoming signal. The incoming signal can be processed by being mixed with the modulation signal at a mixer. The mixing may thus cause various beneficial modifications of the incoming signal, such as noise suppression of the incoming signal, rectification of the incoming signal, demodulation of the incoming signal, etc.

Abstract: The recycling of charge when two or more of the drive lines of a touch sensor panel are being simultaneously stimulated with the in-phase and anti¬ phase components of a stimulation signal is disclosed. To perform charge recycling, a discharge path can be selectively formed between drive lines being stimulated with the in-phase and anti-phase components of the stimulation signal. A multiplexer can be coupled to the driver of each drive line and the common discharge path. When charge recycling is to be performed, control logic can configure the multiplexers to isolate the driver and connect the drive lines being stimulated with the in-phase component of the stimulation signal with the drive lines being stimulated with the anti-phase component of the stimulation signal. The capacitance on the charged-up drive lines can then discharge to the capacitance on the discharged drive lines.

Abstract: Embodiments of the invention include an IC that includes a core used for ordinary operation and a thin power circuit. The thin power circuit can be configured to use very little power. The IC can also include a digital interface and a connection thereto. The IC can initiate transition to low power mode during which the core and various I/O pads can be shut down. However, the thin power circuit can be kept powered up. The thin power circuit can monitor the digital interface for a predefined wake up signal. When the wake up signal is detected, the thin power circuit can power up the core and any powered down I/O pads. The thin power circuit can also include a dedicated power on reset (POR) cell. This POR cell can be distinct than other POR cells used for the IC and can be specifically designed to for efficient operation.
