In the amplifiers described in the four previous chapters, no attempt was made to connect any part of the output signal back again to the input terminals via an external circuit. Such amplifiers tend in practice, however, to exhibit a variable, and therefore unreliable, performance. The ...

Normally, positive feedback is not used for amplifiers. For example, positive feedback is used to provide hysteresis for oscillators and comparators. (If you are interested in this, see the FAQ entry: “How can I provide hysteresis (Schmitt trigger) for a comparator?”...
Amplifiers Feedback - An amplifier circuit simply increases the signal strength. But while amplifying, it just increases the strength of its input signal whether it contains information or some noise along with information. This noise or some disturbance
second-generation current-conveyors and current feedback operational amplifiers (CFOAs). Of particular interest here is the relaxation oscillators built around CFOAs. This is attributed to their higher signal bandwidths, greater linearity, wider dynamic range, simple circuitry and low power consumption....

Folded waveguide traveling-wave tubes (FW TWT) are among the most promising candidates for powerful compact amplifiers and oscillators in millimeter and submillimeter wave bands. In this paper, the nonstationary behavior of a FW TWT oscillator with delayed feedback is investigated. Starting conditions...
