Cascode Amp

01:07:47

Trying to make a cascode amp with a voltage gain of around 65 and having the output voltage swing 2V peak to peak. I'm pretty close but there is just a bit a clipping at the top of the wave. If anyone has any ideas let me know.

If you want an amp gain of 65 to have an output of 2Vpp (1V amplitude), then you need an input of 15.38mV. It looks like your input is currently around 30mV. So that puts your gain around 33 or so. I suggest that at the least you determine what your input voltage will be, what impedance your input needs to be, how much voltage your output needs to be, and what impedance it needs to drive. You figure out the input and output, then you'll be able to start figuring out what components to use, and the gain is almost just a by-product of that.
