    Silvaco Basic question about first mosfet example.

    Attention at your Id-Vd plot, the X axis is "Gate Voltage" not "Drain Voltage". :roll: Change the X axis into "Drain Voltage" axis.

    Current unit for a 2d device simulation in Atlas (Silvaco)

    By default ATLAS simulate 2D structure with device with 1 micron width. You can even consider this is the nominal current (A/micron) of your structure. If your structure wider than 1 micron, eg. 10 microns - current of structure will be 10 times bigger.

    How to calculate junction depth (xj) manually by seeing this mos layout in silvaco???

    The source have Y ~ +2.15 (micron), and the p-n junction (below source) Y ~ +4 (micron), so xj (below source) is about 1.85 micron.

    Handling I/O pins in a microcontroller - problem occurs

    Sorry. I said about pull-up resistor not pull-down resistor.

    loss in current supplied in two circuits-impedance mismatch?

    Re: impedance mismatch You should told more clear, how about output voltage and current of solar cell system , how about input voltage, current of battery.

    Handling I/O pins in a microcontroller - problem occurs

    Re: Handling I/O pins He meaned that output of your sensor maybe isn't strong enought to pull the static of microcontroller's input down to ~0V. And he recommended you changed your pull down resister to higher value (example:33kΩ or 47kΩ) to make the static easier to pull down to 0V.

    [SOLVED] PIC Programmer .. Help

    vpp pic programming I checked it, MCLR pin have 13.35 volt. Maybe when it come to programming stage, it down a bit.

    [SOLVED] PIC Programmer .. Help

    pic programer I use JDM programer version in olimex.com . And I used it to program my 18F252,2550,4550. It worked. My Vpp voltage in programmer is about 13,4V. If you want, you could test with Vpp increasing step by step. @namnq: you tested many progammer, do you know about my case?

    Build easy MPLAB-6 ICD-2 for PIC18F2550

    icd0021 unable to connect with mplab icd 2 I'm finding document "In-Circuit Serial Programming Guide" DS30277d.pdf . But I can't find it in Microchip site. Maybe Microchip rename or del this document. Could Anyone help me find it. Thanks.

    Using high side MOSFET driver

    hip4081 motor I got some Hip4081 . If I using it only for turn on/off motor , not for PWM in controll motor , is my MOSFET in high side going to turn off because charge pump capacitor for Hip fully discharge . But sometime I use my motor in PWM mode . Is it ok ?
