  1. In an NMOS, does current flow from source to drain or vice-versa?

    When a channel exists in a MOSFET, current can flow from drain to source or from source to drain - it's a function of how the device is connected in the circuit. The conduction channel has no intrinsic …

  2. Why do we need NMOS transistors for NAND gate?

    Mar 13, 2021 · The NMOS transistors are unnecessary if you want to implement some sort of current-mode logic where absence of current is a logical zero. If you want to implement voltage-level logic, …

  3. Why choose a PMOS over an NMOS or vice versa?

    Sep 1, 2019 · First and foremost, A PMOS is a "backwards" NMOS (and visa-versa). In an NMOS, in typical operation current flows from drain to source when the gate voltage is higher than the source …

  4. Benefits/downside of discrete high-/low-side NMOS/PMOS and high …

    Feb 28, 2023 · Low-side NMOS High-side NMOS Low-side PMOS High-side PMOS Boot-strap NMOS circuit The basic functionality of those circuits is rather the same. #3 doesn't make that much sense …

  5. pseudo nmos inverter - Electrical Engineering Stack Exchange

    Aug 28, 2016 · The NMOS will leave saturation when Vout < Vin - VTN. It depends on the geometry and the parameters which case occurs first, but at some point the NMOS will leave saturation and the …

  6. mosfet - High-side NMOS for buck converter? - Electrical Engineering ...

    Jun 14, 2021 · In an actual device using NMOS high-side FETs there's a trick to dealing with this issue: use a bootstrap voltage generator to make the high-side gate driver supply.

  7. ltspice - How to do NMOS modeling analysis in Spice - Electrical ...

    Jan 29, 2022 · Here is my circuit in Spice: I want to do a simple analysis of the NMOS like this: What kind of command should I use?

  8. Transconductance of a nmos transistor - Electrical Engineering Stack ...

    May 13, 2017 · Can anyone explain me how I can find gm from this schematic below (for a nmos transistor)when VGS=6V and VDS=6V?

  9. NMOS/PMOS logic vs. CMOS logic - Electrical Engineering Stack …

    Mar 14, 2016 · I know proving condition 1 automatically implies condition 2. But can the same be said for the reverse? Going off of this, in CMOS logic, does the current not matter in determining whether the …

  10. What affirms channel current direction in nMOS and pMOS?

    May 30, 2021 · In circuit designing, it is a common phenomenon to presume that in case of nMOS the channel current flows from drain to source (also seen in schematics), while in the case of pMOS, …
