A common-collector (CC) amplifier is also known as an emitter follower (or a voltage follower) due to the fact that the output voltage "follows" the input by being approximately equal to the input voltage. The amplifier is shown in Figure (a), in which the collector forms a common terminal between the input and output circuits, and resistors R1, R2, and RE are determined by biasing. Capacitors CB and CE are chosen large enough to appear as short circuits at the lowest frequency of interest in the input signal vS. The output voltage vL is taken across the load resistor RL. The small-signal ac equivalent circuit of the amplifier is shown in Figure (b), whose analysis yields the following results:
how to calculate voltage when 3 voltage sources are given?
Calculate the maximum length of an optical fibre that exhibits 0.8dB/km attenuation if the optical output is 10mW and the power launched at the input is 150mW. [Hint: Loss, L=10 lo
Electricity beyond doubt is very useful and essential for us; but if dealt with carelessly, it can prove to be very fatal. It is compulsory for a laboratory assistant to be sure of
Problem: Jyoti Textile is considering whether to add a new product to its range. Machinery costing $280,000 would have to be bought at the start of the project (Year 0). The pr
design and sketch an optimal circuit that takes a 4 bit number and generates an 8 bit output equal to the square of the input
Now you have to digitally implement this circuit. Compute a difference equation which if you implement will behave exactly like this circuit.
a. Describe the meaning of standing wave ratio. What is the formula for it, if the load is purely resistive? Why is a high value of SWR often undesirable? b. Determine how the c
If aluminium and copper pipes are of same length and diameter ... same magnet dropped through them...in copper it takes more time to come out of other end, i myself have done this.
I want to know whether the circuits for both methods(linear polarization resistance and electrochemical impedance spectroscopy) are same or not?
Q. Explain the operation of oscillators. Oscillator is a circuit that changes dc energy from the power supply into ac energy. An amplifier provided with a positive feedback bec
