Abstract: A semiconductor-based stress sensor can include a bipolar transistor device with first and second collector terminals. An excitation circuit can provide an excitation signal to an emitter terminal of the bipolar transistor device, and a physical stress indicator for the semiconductor can be provided based on a relationship between signals measured at the collector terminals in response to the excitation signal. The signals can indicate a charge carrier mobility characteristic of the semiconductor, which can be used to provide an indication of physical stress. In an example, the physical stress indicator is based on a current deflection characteristic of a base region of the transistor device.

Abstract: A semiconductor Hall plate-based sensor can provide information about package stress and can be substantially immune to the influence of magnetic fields. In an example, the sensor can include a Hall plate and an excitation circuit. The excitation circuit can provide signals to respective node pairs of the Hall plate. A measurement circuit can receive information about a first electric signal at a first pair of nodes in response to a first portion of the excitation signal, and can receive information about a second electric signal at a second pair of nodes in response to a second portion of the excitation signal. The first and second electric signals can indicate a charge carrier mobility characteristic of the semiconductor, which can be used to provide an indication of physical stress on the sensor.

Abstract: A system current sensor module can accurately sense or measure system current flowing through a sense current resistor by shunting current through a gain-setting resistor and using an amplifier to measure a resulting voltage, with an output transistor controlled by the amplifier controlling current through the gain setting resistor in a manner that tends to keep the amplifier inputs at the same voltage. The resistors can be thermally coupled to maintain similar temperatures when a system current is flowing. The thermal coupling can include conducting heat from a first resistor layer carrying the current sense resistor to a thermal cage layer located beyond a second resistor layer carrying the gain-setting resistor. This preserves accuracy, including during aging.

CPC classification number: H03M1/1014 , H03M1/002
Abstract: An analog-to-digital (ADC) converter system and method of using the system that can be used in low power situations. The converter can periodically or recurrently turn off a reference standard in order to conserve power and instead using a stable supply source as a reference voltage. A precise conversion for signal from the analog to the digital domain while maintaining a low quiescent current.
