Monostable

NE555 as monostabile

When a falling edge enter the trigger, the output goes to the instable state (high) for a prefixed time.
T_i=1.1·C_i·R_i
The Trigger must go high beefore T_i to avoid unuspected output as at 64ms (the lengh of the pulse is different than T_i).

E-MOSFET input and output caracteristics

The transfer caracteristic (input) is realized by an unique DC-Sweep of (V_GS) from 0V to 10V keeping V_DS constant. On this plot is shown the MOSFET IRF034 threshold voltage (V_GS(th))
To plot the Drain caracteristics 2 DC-Sweep are used: the "Primary Sweep" for V_DS (x-axis); the "Secondary Sweep" for V_GS (parameter).
