DN50 - High Frequency Amplifier Evaluation Board
... High speed operational amplifiers work best when their supply pins are bypassed with RF-quality capacitors. C1, C5, C8, and C10 should be 10nF disc ceramics with a selfresonant frequency greater than 10MHz. The polarized capacitors (C2, C4, C7, and C9) should be 1µF to 10µF tantalums. Most 10nF cera ...

Section I3: Feedback Amplifiers
... We are now going to discuss two specific examples of voltage and current feedback using the common-emitter (emitter-resistor) amplifier configuration. The specific examples chosen were previously introduced in Section D8 (Chapter 7 of your text) when we discussed bias stability and types of biasing. ...

... Vo ( p − p) is approximately 10V. Measure the positive and negative slew rate from the scope face. You do no need to sketch vo for the sine or square wave. 4.) Repeat step 3 for the 318. You should observe a large increase in the gain at the closedloop break-frequency f bc , which indicates that the ...
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.
