Help me with designing a push-pull amplifier

Re: Push-pull amplifier

to match transistor stages generally their W/L is made to match... also the direction of their current flow is made to match...

i didnt understand what you are asking regarding the usage of the capacitor... can u restate it a little clearly....

Re: Push-pull amplifier

Here is ( on the schema ) a three stage common-emitter design. I would like to know how to take off the capacitor between each stage without burning the second stage. What is to consider ?

Re: Push-pull amplifier

actually why do you want to remove the capacitor????

the one main thing you gotta know is that CE amp usually introduces a DC component at the output and if you remove the capacitor in the inbetween stage then the output of the next stage may get clipped if the gain or input is high....

Re: Push-pull amplifier

Finished !!! My push-pull is a simple design with mosfet to control the bias voltage and transistor as output. The input impedance of the mosfet is so high that the lower frequency aren't cut, question ?
