Publication number: 20240128927Abstract: A frequency compensation circuit determines a target calibration count of a fixed capacitor coupled to a processing device. The frequency compensation circuit identifies a current calibration count of the fixed capacitor. The frequency compensation circuit determines that the current calibration count satisfies a threshold criterion associated with the target calibration count. In response to determining that the current calibration count satisfies the threshold criterion, the frequency compensation circuit adjusts a frequency of an internal oscillator of the processing device based on the current calibration count and the target calibration count.Type: ApplicationFiled: October 13, 2022Publication date: April 18, 2024Applicant: Cypress Semiconductor CorporationInventors: Carl LIEPOLD, Austin Chan

Patent number: 10558313Abstract: Systems and methods receive multiple of trigger signals and responsive to each trigger signal transition a sensing block from operating in a first mode to operating in a second mode by turning on power to one or more portions of the sensing block. Operating in the second mode includes performing multiple sensor scans during multiple sensing periods of a monitoring period. Based on performing a first scan during a first sensing period, systems and methods transition from operating the sensing block in the second mode to operating the sensing block in the first mode by turning off the power to the one or more portions of the sensing block. Based on performing a second scan during a second sensing period, of the plurality of sensing periods, systems and methods transition a processing module from operating in a first processing mode to operating in a second processing mode.Type: GrantFiled: October 12, 2018Date of Patent: February 11, 2020Assignee: Cypress Semiconductor CorporationInventors: Andriy Maharyta, Carl Liepold, Hans Klein

Patent number: 6348882Abstract: A signal converter is provided for converting multiple level encoded digital signals into a binary equivalent signal. The signal converter includes a reference voltage generator, a plurality of four-input differential comparators, timing recovery circuitry, and signal conversion circuitry. The reference voltage generator is operative to generate a plurality of progressively larger differential reference voltages. The plurality of differential comparators are each operative to compare magnitude of a differential input voltage with magnitude of a dedicated one of the progressively larger differential reference voltages and produce a differential output voltage having a first logical sense if the magnitude of the differential input voltage is greater than the magnitude of the differential reference voltage, and having a second logical sense if the magnitude of the differential input voltage is less than the magnitude of the differential reference voltage. Each comparator has an offset input voltage.Type: GrantFiled: July 25, 2000Date of Patent: February 19, 2002Assignee: Philips Electronics North America CorporationInventors: John Charles Ciccone, D.C.
