    How and when to use a NMOS and PMOS as current source/sink and voltage source in a circuit?

    as my question state, I am having trouble understanding the circuit using a NMOS/PMOS as a current source or voltage source according to the pins they are connected and also the input and output impedance present when looking at only one pin of the MOS. my lack of understanding comes in the...

    Designing a Delayed MOSFET switch Circuit for Voltage Transfer on a PCB

    I am seeking guidance for the design of a circuit on a PCB board. The intended function of this circuit is to facilitate the transfer of a 24 V voltage from the input to the output through the utilization of a load switch (SIP32429DN (datasheet), 3 A maximum). This transfer should only occur...

    How to connect PMOS in parallel

    Hi, we are designing a 48V high side MOSFET switch and we realised that the our mosfet gets too hot. Our solution is to connect additional mosfets in parallel to distribute the load/heat. But I'd like to ask your how to properly connect PMOS in parallel. I read somewhere that the gates should...

    Small signal analysis of MOSFET circuit

    The other day I got the following exercise on one of my exams: For those who don't speak German, for transistor 1 lambda is 0, but not for the others. The backgate-effekt should be neglected alltogether. I drew the following small signal equivalent circuit (ignore the black texts for now)...

    Power switch PMOS controlled by button or Microcontroller (or both)

    Hello, I´m trying to design an analog circuit to use a push button to turn on an MCU and then use it the same push button to change modes. A "one push button circuit". To achieve that, I used a pmos to work as a switch on the power signal and then used a 2 nmos circuit for or signal circuit that...
