Using a PN-junction diode for temperature measurement usually depends on its 2‑mV/K temperature coefficient. Conventionally, you must amplify and digitize this voltage with an ADC before you can use ...

RF ENERGY harvesting techniques for micro-power can be employed for a wide range of radio frequencies, and the license-free industrial, scientific and medical (ISM) radio bands, such as 915MHz and ...

Connecting an LVDT (linear-variable-differential transformer) to a microcontroller can prove challenging because an LVDT requires ac-input excitation and measurement of ac outputs to determine its ...

Unijunction transistors (UJTs) were common circuit elements several decades ago. A simple ramp generator could be built from a single UJT and a few other components (Fig. 1). 1. In a simple UJT-based ...
