How are MOSFET gate capacitances (Cgs, Cgd) calculated? 6 Your equations are approximations to the capacitance seen between G-D and G-S of a mosfet in different regions of operation and they are derived based on the physical characteristics of the mosfet Keep in mind that the physical mosfet is a symmetric device
Do MOSFETs have voltage drop across source and drain when turned on? Like diode and BJT having around 0 6V drop, is there any voltage drop across the MOSFET drain and source when the MOSFET is turned on? In the datasheet, they mention diode forward voltage drop, but I assume that it for the body diode only
Relationship between Vds and Vgs- MOSFET The MOSFET acts like a voltage-controlled resistor This region is used for switching Saturation (Vgs > Vt and Vds > Vgs - Vt) -- current flows from drain to source The amount of current is proportional to the square of Vgs, and is (almost) independent of Vds The MOSFET acts like a voltage-controlled current source
MOSFET Power Supply Explained - Electrical Engineering Stack Exchange By my understating the MOSFET only amplifies current, not voltage, so how is the output changing with the jumpers? Edit: I understand now that the transistors are working as an amplifier to give a negative voltage potential to the FET I am now struggling to grasp how the current changing from the FET changes the output voltage
