opamp as comparator with waveform
I'm using an OPAMP 741 as a comparator whose output is directly fed to a sqaure-wave inverter's transistor switches. As the magnitude of positive saturation voltage of 741 is not equal to that of the negative saturation voltage , there appears to be some unsymmetry in the output of the inverter voltage waveform.
So, is there a way to make these two saturation voltages equal in magnitude ? Hopefully, this will produce a more symmetrical waveform .
So, please help!!!
