Patent number: 11711068Abstract: A phase shifter for altering the phase of a radio frequency signal is disclosed herein. A Lange coupler is used having reflective ports that are coupled to artificial transmission lines. The artificial transmission lines provide a reflection transmission path, the length of which can be determined by digital control lines. Transistors placed along the length of the central trace provide independent paths to ground that serve to shorten the electrical length of the ATL. Accordingly, by selectively turning the transistors on/off, the electrical length of the ATL can be selected and thus the amount of phase delay introduced by the phase shifter.Type: GrantFiled: November 10, 2020Date of Patent: July 25, 2023Assignee: pSemi CorporationInventors: John Birkbeck, Vikas Sharma, Kashish Pal, Mark James O'Leary

Patent number: 10715123Abstract: Circuits and methods for correction of errors in multi-stage stepwise signal modification circuits. Embodiments of the invention also provide flexibility to correct accuracy errors over a range of conditions, such as differences in signal frequency and/or temperature. A first embodiment includes sorting actual values of a multi-stage stepwise signal modification circuit to generate a monotonic listing of actual values; mapping input codes to a new order of codes corresponding to the sorted actual values; and providing mapping functionality to convert each input code into a mapped output code. A second embodiment includes searching, for each ideal value corresponding to an input code, all actual values of a multi-stage stepwise signal modification circuit for the actual value closest to the ideal value; mapping input codes to a new order of codes corresponding to the closest actual values; and providing mapping functionality to convert each input code into a mapped output code.Type: GrantFiled: June 21, 2019Date of Patent: July 14, 2020Assignee: pSemi CorporationInventor: Mark James O'Leary

Patent number: 10250339Abstract: A calibration architecture that enables accurate calibration of radio frequency (RF) integrated circuits (ICs) chips used in transceiver RF systems in a relatively simple testing environment. Embodiments of the invention include one or more on-chip switchable internal calibration paths that enable direct coupling of a portion of the on-chip circuit to an RF test system while isolating other circuitry on the chip. Some embodiments allow interconnection of switchable internal calibration paths between separate IC chips. Still other embodiments utilize internal switches and antenna mutual coupling to provide over-the-air calibration, alone or in combination with direct signal coupling via internal calibration paths. Periodic self-calibration of an RF IC can be performed after initial factory calibration, so that adjustments in desired performance parameters can be made while such an IC is embedded within a final system, and/or to take into account component degradation due to age or other factors.Type: GrantFiled: October 24, 2018Date of Patent: April 2, 2019Assignee: pSemi CorporationInventors: Vikas Sharma, Mark James O'Leary
