Methods and apparatuses featuring a multiplying injection-locked oscillator are described. Some embodiments include a pulse-generator-and-injector and one or more injection-locked oscillators. The outputs of the pulse-generator-and-injector can be injected into corresponding injection points of an injection-locked oscillator. In embodiments that include multiple injection-locked oscillators, the outputs of each injection-locked oscillator can be injected into the corresponding injection points of the next injection-locked oscillator. Some embodiments reduce deterministic jitter by dynamically modifying the loop length of an injection-locked oscillator, and/or by using a duty cycle corrector, and/or by multiplexing/blending the outputs from multiple delay elements of an injection-locked oscillator.

Integrated circuit having a multiplying injection-locked oscillator

In some aspects of the present disclosure, a touch-panel interface includes a plurality of receivers, wherein each of the receivers is coupled to one or more receive lines of a touch panel, and each of the receivers includes a switch capacitor network and an amplifier. The touch-panel interface also includes controller configured to control switches in the switch capacitor network of each of one or more of the receivers to operate each of the one or more of the receivers in one of a plurality of different receiver modes.

Highly configurable front end for touch controllers

In some aspects of the present disclosure, a method for touch-panel processing is provided. The method includes receiving a plurality of sensor signals from a touch panel, wherein each one of the plurality of sensor signals corresponds to a respective one of a plurality of channels of the touch panel. The method also includes, for each one of the received sensor signals, converting the received sensor signal into one or more respective digital values. The method further includes, for each one of the received sensor signals, performing digital processing on the one or more respective digital values using a respective one of a plurality of processing engines to generate one or more respective processed digital values. The method further includes performing additional processing on the processed digital values.

Methods, integrated circuits and computer-readable media for communicating back-channel data over a data link by modulating the phase or frequency of a clock signal of a data signal transmitted over the data link. Slow modulation of the clock signal allows it to be detected and extracted by a receiver without affecting the integrity or bit rate of the data signal. Some embodiments allow the functionality to be implemented without the use of extra hardware in the transmitter or receiver or either.
