26th May 2020, 22:38Use the power of your mighty internet browser. Try searching for "power supplies". You'll be AMAZED!!!6 replies | 342 view(s)

26th May 2020, 22:32Stupid question, maybe: Why mess around with the sensor side of things, why don't you just modify the output circuit to be controlled by the switch?...2 replies | 257 view(s)

23rd May 2020, 17:12Don’t confuse mains ground with the negative supply terminal; they’re generally isolated.it’s the negative terminal(common) that needs attention.17 replies | 875 view(s)

23rd May 2020, 05:21I would be a little concerned about capacitance. What speed are your signals? Driving into the RC formed by your 1Ks might be a problem. Also, verify...4 replies | 419 view(s)

22nd May 2020, 19:15Yes, but there's also that problematic white protoboard, and another board in the background; are those part of the system?17 replies | 875 view(s)

18th May 2020, 22:21Good answer, but to a different question. Op was asking for buffer, not switch circuit.11 replies | 711 view(s)

16th May 2020, 17:23Yes, a common-collector(emitter follower) would work since it has a high input impedance. But there are better solutions: mosfet, opamp. Show us a...11 replies | 711 view(s)

8th May 2020, 00:58Ok, I plotted gain. It STILL doesn't look like the OP's plot. Or the "ideal" plot. But, here's the problem: OP has defined the sine source with a 2...15 replies | 1021 view(s)

7th May 2020, 18:41The plot came from the simulation. I'm too lazy to actually do the analysis by hand. How do you know it should be gain of 2, other than from the...15 replies | 1021 view(s)

7th May 2020, 17:46Your plot doesn't look right. What point are you plotting? You should be plotting the output. It should look like this:15 replies | 1021 view(s)

7th May 2020, 14:19Why would you think that changing external stimulus would change the response of your circuit? It’s a sine wave, right? How do you know the...15 replies | 1021 view(s)
