Publication number: 20210409024Abstract: An input circuit that recognizes (e.g., buffers) logic level signals (e.g., of an input signal) represented by voltage levels that are lower than a supply voltage of an input circuit, and that exhibits static current draw immunity during stable states of an input signal. In one or more examples, series inverters are provided to buffer an input node and an output node of the input circuit. A voltage domain at the input circuit or output node may be higher than a voltage domain at the input node. Power supply to a first inverter of the series inverters may be turned OFF at least partially responsive to an indication that an output signal is a logic high; and power supply to the first inverter of the series inverters may be turned ON at least partially responsive to an indication that the output signal is a logic low.Type: ApplicationFiled: June 23, 2021Publication date: December 30, 2021Inventors: Sridhar Devulapalli, Daniel J.

Patent number: 9170592Abstract: Methods and systems are disclosed for an integrated voltage regulator with open loop digital control for power stepping. In one aspect, a method for regulating an output voltage includes receiving data indicative of a power setting associated with an identified state of an electrical circuit, the power setting based on a load current demand of the electrical circuit in the identified state, enabling one or more parallel driver segments based on the received data indicative of the power setting. The method further includes sourcing by the enabled one or more parallel driver segments sufficient current to meet the load current demand of the electrical circuit in the identified state while maintaining the output voltage at a predetermined voltage level, and providing the output voltage to the electrical circuit at the predetermined voltage level.Type: GrantFiled: September 5, 2012Date of Patent: October 27, 2015Assignee: Atmel CorporationInventors: Michael Seymour, Daniel J.

Patent number: 8783949Abstract: A self-calibrating, wide-range temperature sensor includes a current reference, impervious to process and voltage, with the current reference mirrored into two oppositely-sized bipolar transistors or diodes. Duplicate current sources are used with a ratio of geometries between them, such that the larger current biases the smaller bipolar transistor (less cross-sectional area) and the smaller current source biases the larger bipolar transistor (higher cross-sectional area). The current source in conjunction with the differential temperature sensing provides inherent calibration without drift while the differential sensing, from the ratio of geometries in the current paths also increases sensitivity.Type: GrantFiled: November 17, 2009Date of Patent: July 22, 2014Assignee: Atmel CorporationInventors: Jed Griffin, Daniel J.

Patent number: 8186601Abstract: A charge pump is incorporated into circuitry of an RFID tag. The charge pump takes advantage of an antenna voltage phase to eliminate the need for a charge pump clock generator. Placement of the charge pump in the RFID circuitry reduces the number of pump stages and eliminates drivers used in each pump stage. In some implementations, an RFID tag comprises antenna circuitry, including a tuned antenna, for receiving an RF signal. Voltage conversion circuitry in the RFID tag is coupled to the antenna circuitry and operable for converting a varying magnetic field produced in the antenna to a voltage source. A charge pump is coupled to output voltage signals of the antenna circuitry which provide the charge pump with a high starting reference voltage and a two phase pump clock.Type: GrantFiled: June 2, 2009Date of Patent: May 29, 2012Assignee: Atmel CorporationInventors: Daniel J. Russell, Albert S. Weiner, Jeffrey S. Hapke, Michael Klein

Patent number: 6317755Abstract: A portable data device (300) having a memory (302) is provided. The memory (302) is segmented into a plurality of sectors (304-312). A backup memory buffer (312) and a plurality of applications (304-310) are programmed into the plurality of sectors, wherein the backup memory buffer (312) is jointly used by the plurality of applications (304-310). A valid state of data is stored in the backup memory buffer (312) prior to performing a transaction for a first application (304). The valid state of data is restored in the first application (304) upon power up of the portable data device (300) in an event the transaction is terminated prior to completion, wherein the step of restoring is independent of a next application in which a next transaction is performed.Type: GrantFiled: July 26, 1999Date of Patent: November 13, 2001Assignee: Motorola, Inc.Inventors: Patrick L.

Patent number: 5428319Abstract: A modified temperature compensation signal (110) is provided in a temperature compensated crystal oscillator (TCXO) circuit (100) in the following manner. A temperature dependent current generator (104) produces a temperature compensation signal (108) whose amplitude changes responsive to changes in ambient temperature. The temperature compensation signal (108) is scaled, based on a plurality of discrete frequency adjust values (212), to produce the modified temperature compensation signal (110).Type: GrantFiled: November 29, 1993Date of Patent: June 27, 1995Assignee: Motorola, Inc.Inventors: Dennis F.
