The Load is a 10R resistor. The simulation shows the circuit is working properly in the right polarity of the power supply. The Zener diode protects the gate from the overvoltage and the load is getting 1.3A with 13.9V.

WebFeb 8, 2016 · If you use the PMOS as a pseudo-diode, the Gate must be connected to the Drain of the PMOS. The Gate/Drain is then the cathode of your pseudo-diode and the Source is the anode. The problem... WebMOSFETs have an intrinsic body diode that conducts current under forward-bias conditions. This current flows from the drain to the source for a PMOS FET and from the source to the drain for an NMOS FET. Whether using an NMOS or a PMOS FET as a low- or high-side switch, orient the device's body diode in the direction of normal current flow. the outbuildings llangaffo

WebHere we see both the gates are set to DC biases, which are actually just diode connected transistors. Therefore, the will want to short circuit these components to ground. Draw the small signal model of the transistor with all nodes connected as they are in the circuit. Here we see that the drain of transistor M1 is connected to the source of M2.
