    Basic Question NMOS Gate Leakage

    Hello, I'm not quite sure about the specification of Gate-to-Source Forward Leakage (I_gss) given in many datasheets of MOS-FETs. I researched its definition and it seems to be the leakage current (for specific gate-source voltage), that flows from gate to source, while drain and source are...

    Electrical switch for a non-chemical battery - How to do it?

    Hi everyone, I’m seeking guidance. I have a tricky situation which I don’t really know how to get out of. I want to design a system which would consume the least amount of power possible. The idea is to have an ESP8266 do a simple task every minute (updating a e-paper display) and sleep the...

    Arduino Mega 2560 controlled MPPT charge controller for small wind turbine.

    I am in the process of designing a MPPT controller for a wind turbine. There are plenty of MPPT boards (with BQ24650 MPPT charge controller ICs) but these are fixed voltage MPPT designs tailored for photovoltaic applications. So I decided to make a simple DC converter (buck boost design, non...

    AGC with FET

    hello, I have to build an automatic gain control using an FET and an Operational Amplifier, for a phototransistor (SFH314) so that when the signal of an IR LED is weak the AGC maintains the signal, and when the signal is strong reduces it, the gate of the FET I have to control it with the...

    Keep MOSFET "ON" for a certain time

    Hello everyone! I'm currently designing a simple circuit which is working as I want but I'd like to make sure that I haven't done any dumb mistake. That's why I'm asking here. I'd like a signal to switch ON a MOSFET in order to activate a relay. This signal is usually low (0 VDC) but sometimes...

    3 questions regarding MOSFET SOI

    What is the parasitic lateral transistor effect (edge transistor)? What is its effect on the Id x Vg curve? What should be done to avoid it? I read the book is not understood this 3 situations? who can help I am grateful. Book: SILICON-ON-INSULATOR TECHNOLOGY: MATERIALS TO VLSI 3rd Edition

    Using MOSFETs to control resistive loads

    Hello everybody! I want to dump energy from some solar panels into heating by using two heating elements (R1 and R2). To maximize the power output from the solar panels I plan to use a microcontroller to change between single heater, series and parallel configurations. Now, I tried to come up...
