WebJul 6, 2024 · The negative feedback reduces the non-linear distortion and effect of noise, controls the output and input impedances, and extends the amplifier bandwidth. The series-shunt feedback, shunt-shunt feedback, shunt-series, and series-series feedback are the four basic feedback topologies. WebNegative feedback (or balancing 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. WebMay 2, 2024 · Negative feedback can be achieved via four different forms. They differ in how the input and output impedances are changed. We have basically two choices when it comes to connecting the input and output of the amplifier to the output and input of the feedback network. We may produce either a series connection or a parallel connection. porsche downtown l.a
