摘要： A temperature sensor that is insensitive to process variation and mismatch is disclosed. The temperature sensor includes a PTAT voltage generator, a sampling and gain boosting circuit, a filter and a controller. The PTAT voltage generator utilizes a plurality of current sources, each of which is in electrical communication with the same diode, or diode stack. The output of the PTAT voltage generator is sampled and amplified with the sampling and gain boosting circuit. The output of the sampling and gain boosting circuit is then filtered using a low pass filter. The selection of the current mirrors, the sampling timing and other signals are provided by the controller. In some simulations, the output from the temperature sensor was accurate to within 1.5° C., using a one temperature calibration process.

摘要： A thermal sensor with non-ideal coefficient elimination is shown. The thermal sensor has a bandgap circuit, a dual-phase voltage-to-frequency converter, and a frequency meter. The bandgap circuit outputs a temperature-dependent voltage. The dual-phase voltage-to-frequency converter is coupled to the bandgap circuit in the normal phase to perform a voltage-to-frequency conversion based on the temperature-dependent voltage, and is disconnected from the bandgap circuit in the coefficient capturing phase to perform the voltage-to-frequency conversion based on the supply voltage. The frequency meter is coupled to the dual-phase voltage-to-frequency converter to calculate the temperature-dependent frequency corresponding to the normal phase of the dual-phase voltage-to-frequency converter. The frequency meter also calculates the temperature-independent frequency corresponding to the coefficient capturing phase of the dual-phase voltage-to-frequency converter. The temperature-dependent frequency and the temperature-independent frequency are provided for temperature evaluation with non-ideal coefficient elimination.

摘要： A charging to digital converter sensor in a CMOS integrated circuit digitizes a sensed property by comparing charging time between two paths and adjusting the charging rate of one of the two paths by increasing or decreasing the amount of capacitance in that path, until both of the two paths have the same charging time to reach respective constant with sensed property and proportional with sensed property reference voltages or currents. Sub nanowatt operation is achieved with preferred circuits. A method directly digitizes, on-chip, a charging time comparison of two ramp voltages that are compared to respective constant with sensed property and proportional with sensed property reference voltages or currents.
