Hi all, what do you call the distribution generated from these steps:
1. Generate a normal distribution with mean = 0 and standard deviation = 1.
2. Make all the negative data from the distribution positive, i.e. magnitude or absolute the number.
3. Plot the new distribution that now contains...
Hi FvM, is the attached figure the correct way to do it?
The op-amp inputs are shorted to ground because if we want to evaluate the effects of the current source, all other sources must be made 0, from superposition theorem, right?
Then plotting the output voltage/current is the output impedance...
Hi all, what we have learnt is that the output impedance of an opamp is very small.
I cannot seem the find this information in the datasheet of the opamp I am looking at.
May I know how can I measure the output impedance of an opamp using only spice?
The datasheet says power supplies from +/- 2.5 V to +/- 6 V, so I think +/- 3.3 V should work.
These are simulated results using TINA-TI, available free from TI.com.
I reran the simulation placing Rf and also changing V1 to 1 V. The DC sweep for Rf from 0 Ohm to 2k Ohm using +/- 3.3 V supplies...
Hi, I have a simple op-amp voltage follower using OPA683. When the op-amp is powered by +3.3 V and -3.3 V supplies, the ouput voltage maxed out at ~200 mV when I change the input from 0 V to 1 V.
But when I change the power supply to +5 V and -5 V, the output follows the input.
Any idea why...
When measuring RF power using a power meter and power sensor, what is the difference between average power and CW power?
For a sine wave type of signal, is the average power and CW power the same thing?
What about for a pulsed signal like GSM, which I suppose there will be no CW power...
Hi all, how do I know what is the maximum frequency that a particular capacitor can handle? Some datasheets I came across don't specify this thing. I need to find capacitors that will be able to work up to 5GHz. Thanks.
