Common Emitter Amplifier Circuit Diagram. As per our directory this ebook is listed as cdawoceapdf 187 actually introduced on 24 jan. The common emitter circuit configuration is used in many areas of electronic circuit design.
Re is set as a pot so the gain can be varied. Common emitter amplifier vsupply 1 0 dc 12 vin 3 0 rc 1 2 10k rb 3 4 100k q1 2 4 0 mod1 model mod1 npn bf 200 dc vin 0 2 0 05 plot dc v 2 0 v 3 0 end this spice simulation sets up a circuit with a variable dc voltage source vin as the input signal and measures the corresponding output voltage between nodes 2 and 0. The below circuit diagram shows the working of the common emitter amplifier circuit and it consists of voltage divider biasing used to supply the base bias voltage as per the necessity.
During positive cycle of input a sinusoidal ac signal is applied at the input terminals of a circuit that cause the forward bias of base emitter junction hence vbe is increased resulting in an increase in ib.
As an audio amplifier as a basic switch for logic circuits as a general analogue amplifier and in many. This is an example of a common emitter amplifier. Common emitter amplifier vsupply 1 0 dc 12 vin 3 0 rc 1 2 10k rb 3 4 100k q1 2 4 0 mod1 model mod1 npn bf 200 dc vin 0 2 0 05 plot dc v 2 0 v 3 0 end this spice simulation sets up a circuit with a variable dc voltage source vin as the input signal and measures the corresponding output voltage between nodes 2 and 0. Working of common emitter amplifier.
