    analog

    You are provided with a 230 V / 50 Hz ac supply, a 6-0-6 centre-tapped transformer and a BJT of dc current gain 150. Biasing the transistor using a supply of 5.6 V (develop your own), (i) design an amplifier of voltage gain 200 i have designed could anyone correct me design as follows Av=200...

    100K preset with AD620 instrumentation amplifier good idea or bad?

    So I am planning to use an AD620 instrumentation amplifier in my circuit. The gain formula is G = 1+(49.4KOhm/Rg), Rg being the deciding resistance value. By that logic if a 100K preset or Pot is set to zero, Gain attempted is (∞ + 1), which besides being impossible is also way above the 10000...

    Amplifier with 500 voltage gain

    I want you make a amplifier with 500 voltage gain and use a amplifier with common emitter, but I can't get a gain over the 100 with any value of resistors. Vdd is 12 V and b is 100

    Exercises with voltage and power

    Can you tell me if my result results are correct, and if there are errors where are they? I used the symbol rms to indicate the root-mean-square, Avo is open-circuit voltage gain, Ap is the power gain, Rl is the load resistance. i stands for input, s for source and o per output. > 1) A sensor...

    What's the right way?? - Antenna Measurements using a NanoVna V2

    This post is "picking the brains of smarter than me" more than anything. It's a simple question, but I can't seem to find a consistent answer to it. I have heard sooo many different suggestions and so many different "right ways" of doing this, that every way I try, gives different results...

    Looking for help for circuit analysis. Troubleshooting a DBX 1066 compressor/gate/limiter

    Hi everybody! Hope you're good! :) I'm strugglin since some days on that nice muscial tool. I've replaced some faulty switches. Replaced them with new one from Mouser. Sadly I've managed to hurt some VIAS connecting both side of the board. Luckilly enough this is just 2 layer board (top/bottom)...
