  • Publication number: 20240154515
    Abstract: A converter system includes a reference buffer buffering a reference input to produce a DAC reference, operating from a reference feedback voltage generated by a reference divider. A tail buffer generates a tail voltage from an input voltage generated from the DAC reference by a tail divider. An R-2R type DAC utilizes an R-2R ladder to generate a DAC output from a code. This ladder has a tail resistor coupled to the tail voltage. A feedback buffer buffers the DAC output to produce a converter reference. A DC-DC converter generates a DC output from a DC input, based upon a converter feedback voltage. A feedback divider coupled between the DC output and the converter reference generates the converter feedback voltage. Control circuitry selectively taps the reference divider to produce the reference feedback voltage (performing gain trimming) and selectively taps the tail divider to produce the input voltage (performing offset trimming).

  • Publication number: 20240151828
    Abstract: A pixel includes a SPAD having a cathode connected to a first node and an anode coupled to a first negative voltage, and a transistor circuit coupled between a supply voltage and a third node, that turns on in response to an enable signal. A cascode transistor connected between the third node and the first node is controlled by a cascode control signal. A cathode setting capacitor is connected between the first node and ground. A readout inverter is coupled between the intermediate node and an output node and generates an output signal. Turn-on of the transistor circuit sources current from the supply voltage node to the cathode setting capacitor, setting a reverse bias voltage across the SPAD to greater than its breakdown voltage. A photon impinging upon the SPAD cause avalanche of the SPAD which, when occurring after turn off of the transistor circuit, discharges the cathode setting capacitor.

  • Publication number: 20240151844
    Abstract: A flash analog-to-digital converter (ADC) receives an input control signal and performs coarse tuning of a frequency of an output signal, produced between first and second nodes having an inductance coupled therebetween. The flash ADC quantizes an operating frequency range for the output signal produced between the first and second nodes as M·?f, where M is an integer from 0 to N?1, where N is a number of intervals into which a frequency range for the output signal is divided, and where ?f is a resulting frequency step produced by the quantizing. The value of M is generated based upon the input control signal and a word controlling switches of a plurality of switched capacitance circuits associated with the first and second nodes to close ones of those switches associated with the control word to coarsely tune the frequency of the output signal.

  • Patent number: 11977971
    Abstract: A device include on-board memory, an applications processor, a digital signal processor (DSP) cluster, a configurable accelerator framework (CAF), and a communication bus architecture. The communication bus communicatively couples the applications processor, the DSP cluster, and the CAF to the on-board memory. The CAF includes a reconfigurable stream switch and data volume sculpting circuitry, which has an input and an output coupled to the reconfigurable stream switch.

  • Patent number: 11978416
    Abstract: Display elements, each having anode and cathode terminals, are arranged into rows and columns. Each row has an anode-line coupled to the anode terminals for its display elements. Each column has a cathode-line coupled to the cathode terminals for its display elements. A switch for each anode-line selectively couples that anode-line to a storage capacitor, and a switch for each cathode-line selectively couples that cathode-line to the storage capacitor. A display driver activates the row driver for a given row and the column driver for a given column. A switch driver closes the switch for the cathode-line for the given column, then opens the switch for that cathode-line. The display driver deactivates the row driver for the given row, after closing the switch for the cathode-line for the given column. The switch driver closes the switch for the anode-line for the given row.
