  • Patent number: 9683904
    Abstract: A temperature sensor circuit has a reference voltage generator that is trimmable at two temperatures for increased accuracy. The reference voltage generation section generates a reference voltage, the level of which is trimmable. A voltage divider section is connected to receive the reference voltage from the reference voltage generation section and generate a plurality of comparison voltage levels determined by the reference voltage and a trimmable resistance. An analog-to-digital converter can then be connected to a temperature dependent voltage section to receive the temperature dependent output voltage, such as a proportional to absolute temperature type (PTAT) behavior, and connected to the voltage divider section to receive the comparison voltage levels. The analog to digital converter generates an output indicative of the temperature based upon a comparison of the temperature dependent output voltage to the comparison voltage levels.

  • Patent number: 9633703
    Abstract: A circuit arrangement and method of reading the logic state of a memory cell in an array of semiconductor memory cells. A data memory cell selected from the array drives a current on a first data bit line in a read operation. A reference memory cell corresponding to the memory cell is activated after the memory cell is selected, the reference memory cell driving a current through the reference data line at a greater rate than that of the corresponding memory cell regardless of the logic state of the memory cell. A sense amplifier connected to the data line and a reference data line determines the logic state of the selected memory cell. A delay circuit activates the reference memory cell after the memory cell is selected and enables the sense amplifier after the reference memory cell has been activated.

  • Patent number: 9528883
    Abstract: Temperature sensing circuitry implemented on a semiconductor integrated circuit that senses the temperature at a site, digitizes the sensed temperature, and then outputs a signal representing such a sensed temperature. The temperature sensing circuitry converts a voltage signal that is proportional to the temperature to a frequency-based signal, which is converted to a digital bit value. A scalar factor is applied to another voltage signal that is inversely proportional to the temperature to produce a scaled voltage signal. The scaled voltage signal is converted to a second frequency-based signal, which is converted to a digital bit value, and then the two digital bit values are compared. The temperature is determined when the digital bit values substantially match.
