Yesterday, 17:24Hi, You know: No signal goes one way, it always needs a return path. And if the return path is long and high impedance the whole signal will be...20 replies | 420 view(s) -
Yesterday, 14:03Hi, PCB layout: See the picture. I showed the current flow loop for the gate current. A good layout: should have as low as possible enclosed...20 replies | 420 view(s)
