    Capture:Where is the electrolytic capacitor and the fuse?

    Hi all! I am using Orcad Capture 9.2 and I am looking for the symbol of an electrolytic capacitor with the curled line (not that one with the two parallel lines) and additionally the symbol of a fuse. Can anybody tell me in which libraries can I find them? Thank you!

    Question about 74LS07

    Hi all! I am confused a little bit with something related with the IC 74LS07. This IC has buffers, isn`t that correct? So let`s choose the first gate and apply +5V at the input (1A). I expect to get +5V at the output of the gate (1Y), right? So why is that not working with my chips? ??? (I...

    Current Sink for LEDs

    Hi everybody! I want to design a project with some LEDs, something like a signboard and I need to use a current sink, which can drive up to approximately 500-600mA. I have thought of using a NPN transistor (for example 2N2222),  but I do not know what the exact circuit should look like. I have...

    Single-ended CMOS Cascode OpAmp Design

    Can anybody help me with the following circuit? As you can see it is about a CMOS OpAmp, with cascode input stage. I want to find a way to bias M3,M4 (Vb) but until now I cannot manage it. Can anybody suggest me a solution for biasing and how to calculate it (I mean the W/L ratio of the MOSFETs...
