Pole-zero compensators are used to modify the magnitude and phase of feedback amplifier loops. This article goes beyond the textbook level of explanation to consider some of the less obvious design ...

In a previous blog entry I demonstrated the use of PID techniques, but a PID is not the only structure of a compensator. The nice thing about a PID is that once you have an implementation of the code, ...

In 1938 Hendrik Wade Bode, who worked at Bell Labs, published his asymptotic assessment of phase margin and gain margin, bearing his name [2]. The Bode plot is recognized for its simplicity and the ...

How to read Bode plots to assess dynamic control behavior of a power-supply design. Observing Bode plots from an example voltage regulator to observe control-loop speed and stability. This article ...
