Hello everyone,
can anyone help me how to design this kind of power amplifier? hardware part is easy, i need just the schematic, or just how kind of transistors will be used with which resistors or capacitors?
This is the specifications of the amplifier:
Amplifier circuit must be 2 or 3 stage amplifier without feedback. Design a circuit which contains a BJT output stage.
Power amplifier:
• 1dB bandwidth: 25 – 35 KHz
• Input signal: 1 v p-p
• Output power: as large as possible, into 20 ohms
• Input impedance: 1 kOhms
• Adjustable gain
• +/- 12 volt supply
• Fuse connector for properly selected fuse
• Appropriate heat sinks must be incorporated
• To be built on a PCB
• Box connectors:
o Banana inputs (red and black) for +/-12V and ground (protected for reverse
voltage)
o 50 ohm BNC input
o 50ohm BNC output
• 60dB boxed attenuator (BNC input and output)
