Can anyone pls explain about how to design this circuit..
===========================================
You must design and build an amplifier with the following characteristics:
1) At least 0.5W output power when used with a 4Ω load, vi = 200mVpk
@100Hz
2) DC power supply of +/- 5V or less
3) Minimize distortion
You must also desig an amplifier with the following characteristics:
1) At least 0.5W output power when used with a 4Ω load, vi = 10mVpk
@100Hz
2) DC power supply of +/- 5V or less
3) Minimize distortion
You must use the parts you are given. If you feel your design would benefit from
additional resistors, you may use them once you have justified your request to the
course instructor. Your justification must include a design that uses only the given
components, along with the improved design that uses the values you are
requesting; you must be able to fully explain both designs.
Along with your components, you will be provided one breadboard per group.
Please return both, the component package, and breadboard, at the end of the
course. You will have to provide the connecting wires you need and power supply
and/or batteries.
You must supply a Multisim / OrCad simulation, input output transfer function
showing the frequency dependency, bandwidth and gain, and 3dB frequencies.
You must also supply the hand calculations showing the DC current and voltage
values and relevant impedances (including the input and output resistances).
