While current-mode control (CMC) remains the much preferred PWM scheme for switchmode power supplies, its advantages aren't automatic. Indeed, ensuring stability in a switchmode supply involves such ...

AGC (automatic-gain-control) amplifiers use the nonlinear characteristics of control devices. The magnitude of the real component in some of their differential parameters changes depending on ...

Despite being well documented, nonlinearity—its theory and applications—is often viewed as a novelty or strange anomaly. Here, we’ll argue the opposite point of view. Nonlinear and negative ...
