Abstract: A driver circuit having an adjustable output signal includes a logic circuit configured to receive an input signal into a first input terminal and an output circuit coupled to the logic circuit, wherein the output circuit is configured to generate, at an output terminal of the output circuit, an output signal having a signal level that changes in response to a signal level of the input signal. The driver circuit further includes a feedback circuit coupled to a second input terminal of the logic circuit. The feedback circuit includes first and second gate terminals coupled to the output terminal and a third gate terminal coupled to a control signal supply, wherein the feedback circuit is configured to control a maximum level of the output signal from the driver circuit based on an operating threshold of the feedback circuit as set by a control signal generated by the control signal supply.

Abstract: A thermal sensor system including at least one thermal sensor, a voltage control network, a current gain network, a current compare sensor, and a controller. The voltage control network applies reference and delta voltage levels to a thermal sensor, which develops reference and delta current signals. The current gain network is used to adjust current gain. The current compare sensor is responsive to the reference and delta current signals and provides a comparison metric. The controller selects a temperature subrange and controls the current gain network to adjust the gain of the delta current signal to determine a gain differential value indicative of the temperature. The controller may select from among different sized thermal sensors, current mode gain values, and control voltages corresponding with each of multiple temperature subranges. Any one or more of these parameters may be adjusted to adjust an operating point for selecting a corresponding temperature subrange.

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.

Abstract: A thermal sensor system which includes a thermal sensor and a voltage control network which applies a reference voltage level and a delta voltage level to the same or different thermal sensors. The thermal sensor develops a reference current signal in response to the reference voltage level and a delta current signal in response to the delta voltage level. A current gain network adjusts gain of the delta current signal. A current compare sensor, which is responsive to the reference current signal and the delta current signal, provides a comparison metric. A controller controls the current gain network to adjust gain of the delta current signal while monitoring the comparison metric to determine a gain differential value indicative of a current ratio between the current signals. The controller determines a temperature value based on the gain differential value. A LUT may be used to retrieve the temperature.
