assignment is to design a pre amplifier circuit with an NPN transistor to be used in a simple public address (PA) system. The pre amplifier is fed from a microphone that produces an average output voltage of 10 mV rms. The amplifier is to operate over a frequency range of 300 Hz to 5 kHz and should have an adjustable volume control. The expected gain of the amplifier is 100. First we are going to design an amplifier for given specifications‚ model the operation of the circuit using h-parameter and r-parameter

For any node of the circuit in I = out I . Note that the choice of “in” or “out” for any circuit segment is arbitrary‚ but it must remain consistent. So for the example of Fig. 2 we have I1 = I2 + I3 . 2. For any closed circuit‚ the sum of the circuit EMFs (e.g. batteries‚ generators) is equal to the sum of the circuit voltage drops:

and nonlinearity and a wide range of signal frequency response. This paper provides a review of the Op-amp theory and a deep analysis of the design and simulation of current feedback amplifiers and its applications. Various conventional amplifier circuits are converted to CFA and are supported with calculations and simulated results. The software used for simulation is ICAP. I. Introduction Analog design has historically been dominated by voltage mode signal processing. This is apparent in the electronics

to implement lead compensators into a circuit‚ a pole–zero pair is introduced into the open loop transfer function. Lead compensator is a component in a control system that improves an undesirable frequency response in a feedback and control system. Besides that‚ it also provides phase lead in its frequency response. Lead compensator also helps to improve transient response and a small change in steady-state accuracy.Therefore‚ modification of the circuit are to be taken place to meet the desired

sampling‚ quantization and frame synchronization. The circuit designed is meant for one-way dataflow. It supports transmission by one user from any analog input. Hence‚ it is not necessary to select between multiple analog inputs using the frequency-division multiplexing technique. In transmitting wirelessly‚ a laser and photodiode are used instead of antennas. This choice is made because it is complex to build a Frequency Shift Keying (FSK) circuit. Without FSK‚ an antenna would need to be 75km long
