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 loa … Details... more...
Analog Design Ideas process input waveforms
This issue’s Design Ideas perform a host of novel operations on input waveforms in the analog domain. In "Comparator detects position of peaks and valleys in a waveform," frequent contributor Marián Štofka of the Slovak Univer … Details... more...
Microcontroller as voltmeter, testing lithium - battery chargers, canceling common - mode voltage, and more
The circuit in "Microcontroller functions as voltmeter," by author Noureddine Benabadji is an extension of his previous Design Idea on how to use an analog input in a microcontroller lacking a built-in ADC (see "Microcontroller, JFET form … Details... more...
