Suitable type of negative feedback permits an amplifier to obtain a higher bandwidth, lower output impedance, higher input impedance and reduce the nonlinear distortions. Gain of amplifiers which use negative feedback is less sensitive to variations in the values of circuit components and temperature. Under certain conditions, the negative feedback can become positive and of such a magnitude as to cause oscillations. Danger of such an oscillation decreases considerably if the feedback loop is designed carefully. This chapter studies the negative feedback in transistor amplifiers. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.eninfo:eu-repo/semantics/closedAccessElectric ImpedanceCircuit ComponentsConditionFeedback LoopsHigh BandwidthHigh Input ImpedanceLow Output ImpedanceTransistor AmplifiersFeedback AmplifiersBook Chapter103N/A99
