    How to begin development on SOC (xilinx)

    ​I don't know whether it is the right place for posting such question or not. This question is opinion based so feel free to share your experience. Background: I had a year experience programming in C, had worked on micro-controllers like PIC for a little time and now working on nvidia-cards...

    [SOLVED] What's the purpose of these diodes in this driver IC?

    Re: Whats the purpose of these diodes in this driver IC If the output is reversed biased then the B would short circuit and it will blows any way. Same is the case with C when input polarity is reverse bias. Correct if i am wrong. You means to say diode A prevents the output transistor because...

    [SOLVED] What's the purpose of these diodes in this driver IC?

    Whats the purpose of these diodes in this driver IC I would like to know the function of these 3 diodes in ULN2803A driver A is used as a suppression diode but i didn't get the purpose of B & C.

    [SOLVED] Need a suggestion on this PCB design

    Someone suggested to bevel the "T" I think all the traces are mitered now

    [SOLVED] Need a suggestion on this PCB design

    Oops, I forgot that; I will add them now. Pour is used as a ground in the above case. +1 On your helpful suggestions, I have modified the design as follows. How can i solve this Right angle ?

    [SOLVED] Need a suggestion on this PCB design

    You are right but my obsession was that the PCB trace pattern should look good :) What i mean by this is that the connectors are not close to the edge of the board. That's what I thought about first but by surfing different threads about 90/45-degree dilema i realized that it really doesn't...

    [SOLVED] Need a suggestion on this PCB design

    I am a noob in PCB design and would like to know about the common mistakes beginners do while designing PCB. Here is a simple PCB which i had made. The problem I am facing is that the connector on the bottom is NOT ON THE EDGE as shown here If I drag these connectors down, the only problem...

    [SOLVED] Why the Footprint of breakaway headers doesn't fit on PCB

    I am trying to place these male headers on my PCB. I have searched for its footprint and print it out on paper but when i try to place the actual header on printed page, there is a small distance error which results in the header pins not actually fitting in the holes. The footprint i am...

    [SOLVED] Calculating the input offset voltage for OpAmp

    What is input referred noise ? The gain shouldn't be Rf/Rin = 22k/10k=>2.2 in the above case ? That was just to know how the OpAmp behaves when both the inputs are applied the same PD, i.e. Zero in this case - - - Updated - - - Edit: KlausS you are right, By neglecting the input bias current...

    [SOLVED] Calculating the input offset voltage for OpAmp

    I have an OpAmp which states that its Input Offset Voltage is 2mV typical but I want to practically calculate the actual offset it will have at the room temperature. So I have connected the circuit in the following manner on the breadboard. The Ouput voltage i got is 4.4mV, so does this means...

    [SOLVED] Why grounding this pin via resistor

    @Fvm: It means that the new OP wouldn't need it as the new ones don't use BJT's. I would like to make the physical circuit in order to know the offset effect it can cause on new OpAmps.

    [SOLVED] Why grounding this pin via resistor

    what if i directly connect this pin to ground. What are the possible issues i may face.

    [SOLVED] Why grounding this pin via resistor

    Why we need this HIGHLIGHTED resistor in this Inverting amplifier circuit, as this pin is connected to ground anyways.
