I'm trying to design a schmitt triger using a 741 opamp. Before building any circuit I thought of simulating it using multisim, but I ain't able to meet the requirements.. My goals was to let the trigger, trigger at top of 2 Volt and with a hysteresis of 1.6V it should trigger at 0.4V (bottom) too. I found these formules (see attachment) But i'm stuck... Such a simple schematic giving such problems Sorry for this stupid question :roll:
