A Class, "A" Amplifier is needed with the following specification:
Collector Current = 5mA
Needed offset voltage across RE= 2V
Lowest input Frequency = 50Hz
Use a BC108B Transistor which has typical parameters:
hfe = 50, VBE = 0.5V, VCE= 4V
1. Sketch the schematic diagram of the amplifier
2. Explain how you a Voltage Gain at 1kHz and what is the value for your circuit?
3. What is meant by capacitive coupling?, why is it used and how have you achieved this in your circuit?
The voltage across a 1 - μF capacitor is given. Which is the sinusoidal expression for the current? a) 30 sin200t b) 70cos (800t - 20°) At what frequency will the re
