... In Lab 3, you built an open-loop DC motor speed controller. The no-load speed of the motor was proportional to the voltage level of the input signal; however, application of a load reduced the speed of the motor. The speed controller that you will build in this activity utilizes a motor-tach in a fe ...

One-Stage Op Amps
... Two decades ago, op amps were designed to satisfy the requirements of many different applications, i.e., the design was to approach an ideal op amp: AV = ∞ , Rin = ∞ , Rout = o In doing so, many other aspects of the performance had to be sacrificed: power, output swing, speed. Old op amp topology: ...

Negative feedback
Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.Whereas positive feedback tends to lead to instability via exponential growth, oscillation or chaotic behavior, negative feedback generally promotes stability. Negative feedback tends to promote a settling to equilibrium, and reduces the effects of perturbations. Negative feedback loops in which just the right amount of correction is applied with optimum timing can be very stable, accurate, and responsive.Negative feedback is widely used in mechanical and electronic engineering, but it also occurs naturally within living organisms, and can be seen in many other fields from chemistry and economics to physical systems such as the climate. General negative feedback systems are studied in control systems engineering.
