WebA buffer amplifier (sometimes simply called a buffer) is one that provides electrical impedance transformation from one circuit to another, with the aim of preventing the signal source from being affected by whatever currents (or voltages, for a current buffer) that the load may impose. The signal is 'buffered from' load currents. WebThe input signal or weak signal is applied across the emitter base and the output is obtained to the load resistor R C which is connected in the collector circuit. The DC voltage V EE is applied to the input circuit along with the input signal to achieve the amplification.

WebJul 10, 2024 · Since it is a parallel resonant circuit, it acts as a high impedance Collector load at its resonant frequency, and as a lower impedance load at other frequencies. The end result is a signal at the resonant frequency is amplified more than other frequencies.
