For a transistor to work as an amplifier we usually use the common-emitter configuration. The figure below shows how the transistor is set up when it is connected in a circuit as an amplifier. In the figure given above, the input is connected in forward-biased and the output is connected in reverse-biased. … See more From the figure that is given above it is clear that on the output side, V0 = VCC– ICRC, where V0 is the output voltage, Ic is the collector current, … See more We have a coupling capacitor that is used to couple the AC component and decouples the DC component contained in the input signal of the amplifier. At the output of the amplifier, the DC component will be invariantly … See more We usually employ CE configuration for transistors as amplifiers because it provides large values of current gain, voltage gain and power gain. Moreover, there is a phase-shift … See more The resistors R1 and R2 form the voltage division circuit to supply the DC voltage to the base of the transistor. The resistors RC and RE control … See more

WebSimple unity gain buffer amplifiers include the bipolar junction transistor in common-base configuration, or the MOSFET in common-gate configuration (called a current follower because the output current follows the input current). The current gain of a current buffer amplifier is (approximately) unity. Single-transistor circuits [ edit] WebThe common-collector amplifier is considered a voltage-buffer since the voltage gain is unity. The voltage signal applied at the input will be duplicated at the output; for this … edgewater goodwill donation hours
