How to Dynamically Adjust Negative Output Voltage Using a Simple Circuit

We currently have standard techniques for generating negative output voltages and methods for dynamically adjusting output voltage. In this article, I will introduce the missing link between these two technologies—a level-shifting circuit that combines them. Applications requiring negative output voltage include: testing and measurement, aerospace and defense, automotive, and medical. A common method to create … Read more
