I have some rough parameters for an amplifier design. I just wanted to confirm that I was thinking correctly in terms of my design approach.
Av=100
RL=10kΩ
Rin=>600Ω
Rout=<8Ω
Design for output swing as symmetrical as possible.
I have total leeway in terms of the configuration. I was going to design a common emitter for the first stage, to get the Av=100. Then use an emitter follower for the output stage to get the Rout=<8Ω. Is it reseasonable to design the 1st stage to get an input impedance of 600 Ω? It looks like I only have a 2N2222 for the design and I am to design for 150=<Beta=<250, in looking at the datasheet the minimum beta is 75, I'm assuming this means the 2N2222 I will be given will have a beta of greater than 150? Does this seem to be a reasonable assumption?
No spec was given on the required output current. The datasheet gave a Icmax of 1 A. I noticed the datasheet said beta is 100 to 300 for Ic=150mA and Vce=10v, I'm to use Vcc=18v, unless told differently should I design the max output current to be 150mA? Thanks for any input.
