Center tap transformer for transistor amplifier. transforms is a electrical energy from one circuit to another without any direct electrical connection. We had to use the transformer to everywhere. but nowadays we can use SMPS circuit also. in SMPS also have the center tap. Amplifier Transistor amplifiers (or solid state amplifiers) are the most common type of amplifier in use today. A transistor is used as the active element. The gain of the amplifier is determined by the properties of the transistor itself as well as the circuit it is contained within. Transistor as an Amplifier Tutorialspoint The load is connected at the collector of a transistor and for a single stage amplifier, the output voltage is taken from the collector of the transistor and for a multi stage amplifier, the same is collected from a cascaded stages of transistor circuit. By definition, it is the total load as seen by the a.c. collector current. mon Emitter Amplifier and Transistor Amplifiers ... An electronic circuit that consists of a transistor (as main component) along with other circuitry and is capable to increase the strength of the weak signal is called as a transistor amplifier.
