I am using a diode to bias a BJT in order to regulate voltage to a load. See attached image (top)
This top circuit in the attached figure works well and this concept of diode regulation cant be changed.
The problem is that if the load fails as an open circuit, all the current is forced through...
Im trying to interpolate time domain data to improve the FFT resolution. Im not sure what Im doing wrong but Im getting a larger amount of bins but not decreasing the frequency spacing between the bins. I think Im doing something wrong or otherwise have made a mistake in theory. It should be...
id like to model a long 50 ohm cable in orcad layout
There is a module called 'tlossy' for transmission line modeling.
Tlossy seems to work under fixed conditions..
However, Id like to have the power supply on one side of the cable.
Then on the other side, a load. The low side of the load is...
hi all.
really struggling with an issue Im having with a power op amp.
We are getting a distortion in the output waveform, a copy of it is below

we are driving a capacitive load...
I would like to add a multiplication element to an orcad capture simulation.k
ideally any frequency mixer IC model could be better than this element..
i can put in two DC signals and get a proper scaled output
however, i get convergence problems when I stimulate it with an AC signal
Ill...
Ive need to isolate wall voltage (powered from small generator) from a EMF generated by a UPS.
It is a large UPS, it is powering a power supply rated for 1560 of which is supplying about 300V and 0.5A to an instrument.
From what I understand, most commercial UPS have a back EMF which is normally...
hello
say I have a coax wire about a mile long that is subject to strains of 1% of the total length.
This particular wire has a resistivity of about 4 ohms per 200ft.
Is there a way to make a strain measurements out of this?.
if could do a bridge into a differential amplifier if needed.
what...
I am making a long cable with many shunt regulators, only 3 of which are shown in the attached figure. The shunt regulators help prevent the whole cable from working if there is a failure. The long cable is similar to Christmas light scenario where if one load or shunt regulator diode may go...
