摘要： A pulse of terahertz radiation is transmitted through a touch panel formed of a dielectric material. The pulse generates an employable evanescent field in a region adjacent to a touch surface of the touch panel. The terahertz radiation has a frequency range between 0.1 terahertz and 10 terahertz. A reflected pulse is generated from an object located within the region adjacent to the touch surface of the touch panel. A position is triangulated of the object on the touch surface of the touch panel, based at least in part on the reflected pulse.

摘要： A mixed signal device includes an analog circuit and a digital circuit coupled to the analog circuit. The digital circuit includes a component that samples a signal at a sampling rate that is dynamically variable by the digital circuit based on the bandwidth of the incoming signal. The digital circuit is to automatically assert a signal to the analog circuit to change a bias current of the analog circuit based on a change to the sampling rate in the digital circuit.

摘要： An analog-to-digital converter (ADC) includes a first comparator, a second comparator, and a decision timing comparison logic unit. The first comparator is configured to output a first output voltage and the second comparator is configured to output a second output voltage during a same binary algorithmic iteration of the ADC. The decision timing comparison logic unit is configured to identify a first polarity of the first output voltage and a second polarity of the second output voltage and, if the first polarity is equivalent to a second polarity, to insert at least one redundant capacitor for a next binary algorithmic iteration of the ADC.
