My circuit has an output impedance of 2.2KOhms and its output is fine.
But when i connect this output to the input of another circuitry (whose input resistance is 22 Ohms) the signal gets attenuated.
I have designed a buffer using a BJT. still the negative portion of the output gets clipped. plus the transistor heats up after a while.
I also worked with unity gain buffer amplifier using opamp, but no use!
i want a voltage level of +1 to -4 sinosoid..
what should i do?
