    Check my FET switch design

    FET Design question Hello, The C+ pin will be driven to +5V by GP5 (charging process), and it will be 0V when GP5 driven to low (discharge process). AN1 will always in input mode... Well I see this is what you have told me... so I will guess I need a relay anyway. And I see I'm not quite...

    Check my FET switch design

    Hi all, I'm doing a design to check the capacitance of a capacitor... And here is a working design that I used some time ago... However now my new project need to check 2 capacitors. I think I can change to a PIC that have 2 comparator. But I want to leave some flexibility as a provision for...

    Some FET parameters question

    fet idss Thanks! Ian. Still I didn't get much from what you said. For example Idss (as you mentioned when Vgs=0V). In this case, the FET is off, right? Then an ideal FET should have Idss=0?

    Some FET parameters question

    idss fet Hello, What is the meaning of Idss (Zero-Gate Voltage Drain Current) of a FET. Is it the smaller the value, the better the FET? Also what is Vgs, the smaller the better? Thanks & best regards.

    18F452 and RT8019. Is it ok for TCP/IP comunications?

    tcpip para 18f452 Microchip did offer you their free TCP/IP stack. Now the C18 compiler is offered as Student Edition and you could use it after expire of 60 days try period. Added after 59 seconds: Also check their demo board. You can find the schematic in the user's guide.

    How to connect a condenser mic to pick up voice?

    Condenser MIC Dear IanP, Thanks very much. OK now I get something to work with. But Can anyone please explain the circuit. For example the purpose of R1, R2, R3. I think C3 is for coupling purpose. But what about C2? Thanks.
