Hi Tasting_fan, I think you have to drive an input of around 3.3 V to make the two MOSFETs conduct alternately in order to get an inverted output. Also see that you tie the substrate of the P MOSFET to Vdd (3.3V) and N MOSFET to ground.

I have two MOSFETs (MOSFET-P and MOSFET-N), one power supply of 3.3V and one impulse generator which gives out rectangular waves of 1 kHz. But the result is wrong! The input has a range from 0V ¨C 1V, that?ˉs OK. But the output only from 3.072 to 3.300V. Why is it not zero? > > > > Best Regards > > Tasting_fan > > > > --------------------------------- > DO YOU YAHOO!? > ???￠?a・?Góê??￡-?D1úμúò????Tà???óê?té§è?3?′óóê?? > > ____________________________________________________________ > You are subscribed to the PEDA discussion forum > > To Post messages: > mailto:[email protected] > > Unsubscribe and Other Options: > http://techservinc.com/mailman/listinfo/peda_techservinc.com > > Browse or Search Old Archives (2001-2004): > http://www.mail-archive.com/[email protected] > > Browse or Search Current Archives (2004-Current): > http://www.mail-archive.com/[email protected] > ____________________________________________________________ You are subscribed to the PEDA discussion forum To Post messages: mailto:[email protected] Unsubscribe and Other Options: http://techservinc.com/mailman/listinfo/peda_techservinc.com Browse or Search Old Archives (2001-2004): http://www.mail-archive.com/[email protected] Browse or Search Current Archives (2004-Current): http://www.mail-archive.com/[email protected]
