Download (free) PSpice9.1 to investigate circuit problems. Good fun too, far easier to see what changes will work!
Clipping is caused by excessive gain. Your first stage on its own has gain far greater than 10 V/V, and so does the second. Other complications: the second stage is loading the...
230v to 5v without transformer circuit
DO NOT USE the circuits suggested in the link given by IanP. THEY COULD KILL YOU. In my opinion it is irresponsible of Microchip Inc to publish those circuits (they do mention the danger unless you use an isolation transformer, but why then call it a...
