    摘要: A single event effects (SEE) immune linear voltage regulator includes an input node, an output node, a first transistor control logic, a second transistor control logic, a first transistor, and a second transistor. The regulator is configured such that when the first transistor is operating in linear regulation mode, the second transistor automatically operates in saturation mode, and the voltage at the output node is controlled by the first transistor and the first transistor control logic to be substantially equal to the first reference voltage. Conversely, when the second transistor is operating in linear regulation mode, the first transistor automatically operates in saturation mode, and the voltage at the output node is controlled by the second transistor and the second transistor control logic to be substantially equal to the second reference voltage.

    摘要: Systems and methods for an auto-ranging temperature sensor are provided. In at least one embodiment, a system for sensing and measuring temperature comprises at least one analog signal amplifier that generates an amplified analog signal output based on an analog signal from at least one of a biased thermistor circuit and a calibration circuit and a digital to analog converter that generates an analog offset signal as an input to the at least one analog signal amplifier, wherein the analog offset signal shifts the amplified analog signal within an analog to digital converter input operating range when the amplified analog signal is equal to or greater than a limit of the analog to digital converter input operating range, wherein the analog offset signal is determined based on the magnitude of the amplified analog signal.
