INTRODUCTION Input transducer such as microphone or audio signal, pressure sensor, and humidity sensor produces small electrical signals. For reliable processing, any small signal needs to be amplified. The circuit used for boosting electrical signals in a prescribed manner is termed amplifier. A good linear amplifier can be made from simple components eg. BJT/FET, resistors and capacitors. PURPOSE This assignment is intended to provide an experience in designing and simulating a linear amplifier to meet certain design specifications. DESIGN SPECIFICATIONS You are required to design an audio amplifier that meets the following design specifications: • Proper Q-point • • • 130 Load Resistance (R₁): 4.7 k Mid-band Gain (A.) ≤ 1501 Input Resistance (Z): > 1.2 k Supply Voltage: +15 V Low cut-off frequency, fi: ≤ 100 Hz PREPARATION Before simulating the circuit using Multisim, theoretical explanation and calculation should be carried out to ensure correct operation of the designed circuit. DOCUMENT Report should contain: a) Circuit Specification b) Manual Calculation c) Simulation Results d) Discussion & Conclusion i. Comments on dissimilarities/similarities between calculation and simulation.
