gain is between 10dB to 20dB
The voltage or power or current gain?
I will say that:
the circuit output resistance looking into the collector should be >5x smaller than the load resistor and
the resistance looking into the circuit input should be >5x greater than the impedance of your input coupling capacitor at the freq. of interest and
you should first pick an equivalent circuit for your transistor, something with at least one ideal diode in it and
the Vbe at turn-on for a silicon transistor is ~0.5 v and it is fully on at ~1 v and
for temp insensitivity RE should be >5x the internal Re of the transistor [which value depends on the emitter current according to an inverse relationship containing a 26 in the numerator] and
it would help if you were conversant with Leon Charles Thevenin and
the current through R1 and R2 should be >5x than the current into the base and
if you think in terms of KΩ rather than Ω it will probably go easier and
using resistors of 10% or 20% tolerance are probably good enough since your gain spec has quite a wide interval.
What I'm getting at here is that you should think in terms of 1.0, 1.2, 1.5 or even more widely spaced resistance values, rather than 1.0, 1.1, 1.2, 1.5, and
Speaking of your own effort, for extra credit [and to redeem your reputation on this forum], three questions:
.....Are the paragraphs in this post, and these questions, arranged in any particular order?
If so, what is the order? Why this order?
.....Resistor values are evenly spaced on a
a) linear scale?
b) log scale?
.....What's with the 5x stuff?
Why so long-winded? I need practice in tech writing in case I ever get another engineering job. . .
Nice schematic!
