Basic Ce Amplifier Circuit

You can also make the circuit in the breadboard.

Basic ce amplifier circuit. Calculate the maximum collector current ic flowing through the load resistor when the transistor is switched fully on saturation assume vce 0. Next common emitter amplifier. Simple logic common emitter amplifier. When only one transistor with associated circuitry is used for amplifying a weak signal the circuit is known as single stage.

Here are some pictures for making the circuit. Device input impedance zb hie circuit input impedance zi r1 r2 zb device output impedance zc 1 hoe circuit output impedance zo rc zc rc circuit voltage gain av hfe hie rc rl circuit current gain ai hfe. Let us see the working of ce amplifier with the designed values in simulator see the above image to understand the result of amplification i had used signal generator as input circuit signal generator acts as input source for ce amplifier the output ac signal from signal generator is 2v you can notice this from above picture that is simulated result at the output of ce amplifier there is a multimeter connected to measure the amplified voltage the 2v input signal is amplified to 6v at the. Non inverting amplifier circuit 9.

The typical ce circuit performance is summarised below. The figure given below shows the basic circuit of a transistor amplifier. I have made the simple basic audio amplifier circuit in the pcb for making the circuit as simple as possible. But there may be loose connection so i have directly soldered all components.

2 common base amplifier the basic circuit is shown in figure 3 2 and is quite similar to the common gate circuit from the. Let us see how a single stage amplifier is built which is the basic for a multi stage amplifier. It is typically used for driving a load from a digital output from the previous stage. The circuit shown consists of two stages of amplifier in common emitter topology.

An common emitter amplifier circuit has a load resistance rl of 1 2kω and a supply voltage of 12v. A number of single stage amplifiers are cascaded to form a multi stage amplifier. Transistor amplifier circuit as shown in the figure above we apply input signal or the weak signal between the emitter base junction and takes the output across the load r c connected in the collector circuit. Npn bjt amplifier stages.

So there will not be any loose connection. Most transistor amplifiers are of the common emitter or ce type circuit due to their large gains in voltage current and power as well as their excellent input output characteristics.
