hello ,
I would like to know if it is better to use OPamp or single ( or cascading BJT) to amplify a 1v pk-pk to 12v pk-pk using a 12v source.
The frequency should be from 0 to 1mhz.
I am using the circuit found here:
https://forum.allaboutcircuits.com/attachments/common-emitter-speaker-amplifier-02-png.160975/
After tweeking, I get about 9v pk-pk at about 20khz , but when I go up to 100khz it falls to 7v pk-pk
Otherwise the signal is not clipped or distorted. with that circuit.
Would I be able to get what I want using more complex circuit , or using OPamp ??
Thanks
Ken
