How do I calculate the resistors required for the gates, in order to lower the voltage to 2V? Do I just assume max current (16mA) will flow there? Can I just take a multimeter, connect mosfet to 5V and GND and see the current flows to the gate? Also, Why is M5's drain almost and not exactly 0V? Linear equations for nmosfets tells Vds>0, and for my case all the voltage drops on the resistor and leds. Is it enough to just apply 2V on each gate, without making it having Vd>0 for every mosfet? | |
