- Added ADC Improves Analog Square-Root Extraction AccuracyKnown devices for taking the square root contain an operational amplifier and a multiplier connected in a feedback loop. The accuracy of these devices depends on the method of building the multiplier, with the most accurate using logarithm and anti-logarithm functions. However,...Oct 18, 2022
- Controlled power supply increases op amps' output-voltage rangeIncreasing the output voltage of IC operational amplifiers usually involves adding high-voltage external transistors. The resulting circuit then requires correction to retain its operating characteristics. This correction is difficult, especially for precise amplifiers. This...Jun 28, 2020
- Simple Components Increase Precision of Analog-Division CircuitThe example analog-divider circuit presented in this article reduces the error to less than ±0.02%, based on the resolution of both DACs Despite the availability of FPGAs and microcontrollers, the historical use of analog circuitry to implement some arithmetic...Oct 27, 2015
