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.

Package stress sensor

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.
