Patent number: 9810585Abstract: A semiconductor device that may include at least one temperature sensing circuit is disclosed. The temperature sensing circuits may be used to control various operating parameters to improve the operation of the semiconductor device over a wide temperature range. In this way, operating specifications of a semiconductor device at worst case temperatures may be met without compromising performance at other operating temperatures. The temperature sensing circuit may provide a plurality of temperature ranges for setting the operational parameters. Each temperature range can include a temperature range upper limit value and a temperature range lower limit value and adjacent temperature ranges may overlap. The temperature ranges may be set in accordance with a count value that can incrementally change in response to the at least one temperature sensing circuit.Type: GrantFiled: April 30, 2014Date of Patent: November 7, 2017Inventor: Darryl G.

Patent number: 9667259Abstract: A current-to-voltage converter receives a current which varies with temperature according to a selected one of two or more temperature coefficient factors and converts it to a temperature-dependent voltage to be used as a control signal to a varactor in a voltage controlled oscillator, VCO, to compensate for temperature-induced frequency drift in the VCO. A feedback arrangement with hysteresis is provided for controlling the selection of the temperature coefficient factor and operates by comparing the temperature-dependent voltage with a reference voltage. The reference voltage may be pre-set and equivalent to a known operating temperature. A switching signal is generated when Vout approaches the reference voltage and in response, a control module generates a selection signal for selecting a different temperature coefficient factor.Type: GrantFiled: November 22, 2013Date of Patent: May 30, 2017Assignee: NXP USA, Inc.Inventors: Birama Goumballa, Cristian Pavao-Moreira, Yi Yin

Patent number: 9631585Abstract: An automated method for diagnosing an EGHR having a coolant path, an exhaust path, a heat exchanger, and a valve. The coolant path passes through the heat exchanger and the valve selectively directs the exhaust path through the heat exchanger. The method includes monitoring an inlet temperature and an outlet temperature of the coolant path, determining an instantaneous coolant power from the monitored inlet temperature and outlet temperature, and integrating the instantaneous coolant power to determine a total energy recovered by the coolant path. The method monitors an instantaneous exhaust power, determines an instantaneous available EGHR power from the instantaneous exhaust power, and integrates the instantaneous available EGHR power to determine a nominal EGHR energy. A differential is calculated between the nominal EGHR energy and the total energy recovered by the coolant path. If the calculated differential is greater than an allowable tolerance, an EGHR error signal is sent.Type: GrantFiled: September 11, 2013Date of Patent: April 25, 2017Assignee: GM Global Technology Operations LLCInventors: Paul S.
