    C2073 Transistor is hot on standby and the channel is silent. Why?

    The power button of the device was broken and the fuse was burned. So, I changed the fuse, and then I directly connected it over the switch. It can be turned on and there is sound, but I accidentally found that there seems to be a channel that is silent. I changed the input terminal, but it...

    1986 Ford Ranger Wiring

    So I bought a 1986 Ford ranger that needed the body harness completely rebuilt . As I'm ripping out the old harness I noticed something that looks like a wire nut with about 6 wires inside of it. Has anyone seen anything like this? Was this Normal for fords back then ? Or was this the result of...

    Understanding two Multivibrator models

    Hello, I simulated the two multivibrator models in CMOS technology using the cadence tool. I was expecting the model 2 with Schmitt trigger(ST) will show robustness in PVT (Process Voltage temperature) analysis as compared to model 1 due to ST. But this was not the case both the Models shows the...

    Kirchhoff Voltage Law in a two port network

    In a tutorial about h parameters of a two port network I find the below snippet unable to grasp. According to KVL, the total voltage in a loop is the algebraic sum of the individual voltages. But why in this tutorial ( equation 1 in below image ) it's given so. It should be something like V1 =...

    LNA design in AWR

    AWR schematic uses 2x25 and 2x50 Transistors from .15um WIN PE15 process to design a LNA that operates in Ka-band. Can I use the same design for Ku band from Ka design? If yes, why can we use it? How can I change it to be a KU band (12-16Ghz)? I have attached the awr file if needed. I would like...

    Homemade Multi Drill

    Hi, I'm thinking of making a multi drill for wood drilling, that uses anywhere from 6 to 9 9V or 12V DC motors. These motors would be wired in parallel, with one battery source. I'd mount a drill chuck on each of the motors shafts for a drill bit. Now, I need a little bit of help from you. Do...

    Help me understand what is happening with my NGSPICE coding..

    The thing is, I am confused with rawfile and .print card (spice.out file). There are like 3 options for rawfile generation: NONE,COMPACT and ACCURATE. While I am using NONE with the .print card the result is going inside a .out file without generating a rawfile. But when I am using ACCURATE or...
