This month’s Tune-Up column, which concludes a three-part series on position loops, addresses feed-forward gains. Motion control systems often use feed forward to speed up the response to rapidly ...

In a nonlinear world, the challenge of advanced loop tuning is to keep continuous and batch processes, as well as discrete operations, functioning cleanly and productively without unplanned downtime.

How Stable is your Op Amp or FDA design? One of the most important aspects of any end system design is to understand and improve (if necessary) the nominal phase margin for each stage. Since the early ...

Loop analysis of analog and mixed-signal discontinuous systems, such as PLLs, delta-sigma converters, switched-capacitor filters, PWM amplifiers, and switch-mode power supplies, presents a unique ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...

Current-feedback (CFB) op amps have earned their reputation in many applications that need bandwidth, without compromising other noise and high-speed characteristics. They have served these needs ...
