Excuse me each great god, diode D1, D2 is stem what of-CodePudding

CodePudding user response:

To learn and looking at how like regulator tube

reference 1st floor qq_32534981 response:

learn, look at how like stabilivolt

Is a schottky,,,,,,,,

CodePudding user response:

The existence of D2 Vio must be greater than to the D2 is opened only when a voltage Vgs MOS, this is equivalent to promote the open voltage MOS, should be to prevent the Vio too low conduction MOS,
D1 role should be to prevent the VCC power, Vio for high electric current flow backward at ordinary times, and at this point may MOS misleading,

CodePudding user response:

The applications of Nmos circuit

1. The effect of two regulator tube, on the one hand, is to protect, one thousand current flow backward, can guarantee the Nmos from being damaged,

2. Nmos conduction conditions related to consider: V_ioinput & gt; (V_D2 threshold voltage + Nmos threshold voltage) to conduction

CodePudding user response:

The counter-attack or move,,,,,,,,

CodePudding user response:

To prevent the protection, to prevent current flow backward
