Design Ideas spark a variety of functional control circuits
If you need only a few nonvolatile gates, consider using a component common in analog- and mixed-signal systems, the digital potentiometer, instead of a PAL, GAL, or CPLD, as described in "Nonvolatile digital potentiometer gates logic signal."The circuit of "Soft-limiter circuit...

Design Ideas conquer power supply applications
A software solution is the simplest way to compensate the system offset when interfacing a resistive bridge sensor with an analog to digital converter (ADC) powered by a +5V single-supply power source. "Circuit compensates system offset of a load-cell-based balance" shows how to achieve hardware compensation using a microcontroller which on power-up starts a software routine to reset t...
