Common Emitter BJT Amplifier Design Current Mirror Design


Some Random Observations
Conditions for stabilized voltage source biasing
Emitter resistance, RE, is needed.
Base voltage source will have finite resistance, RB.
needs to be much larger than RB.
Small RB - relative to RS - will attenuate input signal.
Larger RE permits larger RB, but results in lower gain.
Gain = -RC/RE for RE >> re.
Split RE with bypassing increases gain.
Requires large bypass cap ....etc

power amplifier circuit diagram



Circuit Description
There are many instances where a simple and reliable power amplifier is needed - rear and centre channel speakers for surround-sound, beefing up the PC speakers, low powered tweeter amplifier, etc. For those who want to build their own 'Gainclone' amplifier, this will certainly do the job :-)
This project (unlike most of the others, but in a similar vein to Project 19) is based almost directly on the typical application ci ....etc

Audio Amplifier Circuit



In the first part of lab#1 you will construct a low-power audio amplifier/speaker driver based
on the LM386 IC from National Semiconductor. The audio amplifier will be a selfcontained, battery-operated component. In the second part of the lab you will construct a
microphone circuit using a compact electret condenser microphone cartridge. These circuit
modules are important building blocks of many audio communications systems, and will be
used in our ultrasonic transceiver system. ....etc

Automatic temperature controlled fan
Here is a scheme through which the fan can be linearly thespeed controlledautomatically, dependingon the room temperature. The scheme is effective because it ishighly control thyristors forpower. Alternatively, samecircuit can be used to automatically control AC temperaturecontrolled.In this diagram, temperature NTC thermistor is sensorused, i.e. one Havinga multiplier negative temperatures. The resistance of the thermistor in Thevalue 25 with the isabout 1 kilogram-ohm.Op Amp A1 essentially works for ASI t ....etc
