Hello all,
Me and my group are doing a design project right now and we are a little stuck on the question, ok very stuck. The question is to:
Design a multi-stage audio amplifier for delivering an average power of a minimum of 200 mW to an 8 Ohm speaker from a microphone that produces a 10 mV peak-peak sinusoidal signal and has a source resistance of 1 kW. Use commercial NPN transistors available in our lab for your design. Analyze the frequency response for the amplifier as well. Design such that the upper 3 dB frequency is at least 50 kHz, and lower cutoff frequency below 25 Hz. Show your design, calculations, as well as simulation results in your report. Use base-emitter junction capacitance and base collector junction capacitance values from the device spec sheet.
We are not very sure on where to start so any help would be very appreciated.
Thanks alot.
