Yesterday, 23:07Hi, Take a piece of paper and draw the exoected currents. You will soon find out that your information is no sufficient. * I assume the 220V,...2 replies | 61 view(s) -
Yesterday, 22:49KlausST replied to a thread stretching the 0 pulse of a digital output with a certain T in Analog Integrated Circuit (IC) Design, Layout and FabricationHi, In post#3 you talk about 50...100ms. Now you talk about 40ns. Why? This is more than a million factor away... Klaus12 replies | 309 view(s)
