Feb 14, 2024 · Discussion on using NMOS and PMOS as current sources, sinks, or voltage sources in circuits, addressing challenges and pin configurations.

Mar 9, 2025 · The PMOS circuit is powered by 14VDC and is using a 2n3904 to switch the Gate on the PMOS. The gate is going from 14v to 0 v, but the Drain is only going from 13.98v to 13.38v.

Jun 7, 2023 · The PMOS MOSFET chosen is about as good as it gets for PMOS esp in a TO-220 case. There are some better ones (sub 10mOhm) in a SMT DPAK or similar case but heatsinking those is …

Jun 17, 2024 · The PMOS should provide voltage across this load for a very short period of time (100us-150us). During switching, I have observed that the MOSFET works absolutley fine during ON state, …

Jan 11, 2012 · The problem I'm having is trying to get the pmos to act as a switch and connect the two resistors. The gate is connected to a microcontroller logic pin with a +5v high output. 3.7 volts is on a …

Oct 29, 2024 · HI. I am trying to design a CMOS Inverter. NMOS turns on and off as expected. However, PMOS does not fully turn off

Sep 2, 2016 · This is the formula in my lecture note for NMOS ] for PMOS, is it something like this? I cant seem to find PMOS formula for this on the internet. Most of...

Feb 13, 2018 · That is, if I want to make the PMOS conducting, I have to apply any voltage between -4V to -20V across source and gate terminals. In a buck converter the source of mosfet is connected to …
