Programmable logic leads the pack
Given its flexible nature and popularity, it's no surprise that programmable logic figures prominently in a growing number of Design Ideas, including two in this new batch. In addition, EDN readers show us how to build a cheap and easy inductance tester, add a manual reset to a standard three-pin-reset supervisor, and obtain hex-code values for a microcontroller's ADC voltages.Jeremy Willden of ad hoc Electronics, Pleasant Grove,...

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...

Design Ideas cruise the analog domain
This issue's clutch of Design Ideas emanates from the analog electronics domain. Frequent contributor Marián Štofka scores a double with, first, "Paralleling decreases autozeroamplifier noise by a factor of two." Štofka parallels all four auto-zero amplifiers in an Analog Devices AD8628 and proves that t... (more) Details... more »
