Voltge is like the pressure of water and current is like the flow of water. voltage source means measure the pressure of water at that point and current source means measure the flow of water at that point rather than measure the pressure.
In Spectre, the sine voltage source have the following parameters: offset, amplitude, AC ampltude, DC amplitude; What is the difference between: amplitude and AC amplitude? What is the difference between: offset and DC amplitude? Is my understanding correct? (1) amplitude and offset is for TRAN analysis. (2) AC amplitude is just for AC
Dear Sir: May I just use valtage source to get the S-para in Driven Model? You can use voltage source, if you want to look at the EM-field pattern, only! For S-parameters getting you need to use Lumped or Wave ports.
just remember it this way: an ideal current source is represented by a nortons model:a current source in parallel witha a resistance,so when this parallel resiatnce becomes infinite then the whole of the current sourced by the current source reaches the desired location or load resistor which is the usual destination. (...)
Yes what you say is true and makes sense. An alternative to a voltage source will be a controled current source. source Inductance will influence maximum current rise rate, but this don't give bether results!?
i hav a transformer that gives 16.38 V rms without load, and 12.6 V rms @ 300 ma which of those values do i use to design a regulated dc voltage source that would give me 310 ma at 12 v?
I am going to design a programmable voltage source, the requirements is output is +/- 15VDC, 50 mA continuous 0.04%+100uV accuracy. But current DAC chips only can output +/- 10VDC, what I can do with it?:cry: Thank you.
A DC voltage source develops 10 V DC at its output terminals. A DC current source that you found at the flea market develops 10 A maximum when properly loaded. Is the first device a high-resistance device, or a low-resistance one? How about the second device?

Hello I want to construct a hi impedance voltage source,(0-1V) for which I identfied 1.5V battery with a external 1Gohm resistor in series, and a variable resistor accross which i will get required voltage. is this sufficient or any other considarations? Thankx --Babesh
1. The input impedance of a MOS transistor is near infinity near DC. As you go up in frequency it looks like a capacitor. Going further up there is a real part. 2. In your simulator (or in your breadboard use a current probe) take the ratio of the gate AC voltage to the gate AC current.

Hi, I am analyzing the effect of noise on my system. For this I want to put a noise source at the input of the system. Can anybody tell if there is any voltage source in Cadence which generates noise. I want white gaussian noise. thanks sarfraz
If you want to use for PSpice simulation in OrCAD, use a bridge network circuit based on 1n4001/1N4007 and connect to DC point. Try to keep the offset as 0V or specified voltage inorder to get exact DC in simulation. ..
Yes, LC circuit can resonate with a square wave voltage source, because square wave is a sum of sinusoid's (Fourier approximation). LC circuit resonate on the basic frequency (square wave frequency) and the other waves with higher frequency are suppress, so we can observe only the basic frequency sinusoid in LC circuit...
hmm .. dn knw much !! bt 1>u cn use a voltage source followed by a comparater to make a square wave gen .
Can someone help me how do u put a sinusoidal transient voltage source with zero offset and a frequency of 10khz in pspice?
You could use a flyback. Take feedback off the 5V,and use a secondary winding to provide Vin for a programmable regulator. I'm Not sure this is what your trying to do but Here is an example of a current to voltage converter. fig will probably have to use an additi
S parameters are independent of voltages for linear devices. use a lumped port instead.

Sorry, the inverter is voltage source inverter type, i saw in Rashid book, The VSI generates an ac output voltage waveform composed of discrete values (high dv=dt); therefore, the load should be inductive at the harmonic frequencies in order to produce a smooth current waveform. A capacitive load in the VSIs (...)

Hi all Just wanted to know if there is any way to calculate the impedance of a structure when excited by a voltage source in HFSS. I tried running a simulation and all I get are field values at each frequency point. There are no other variables for plotting in the results menu. Is there a way to calculate the impedance of the structure using the
I have been trying to calculate the impedance of a dipole pole antenna that is excited by a voltage source in HFSS v9.2.1. I can use the fields calculator to calculate the current at the center of the voltage source line. I should then be able to get the impedance by dividing the voltage by the current. I (...)
if you want to check the power consumption of your circuit from an ideal voltage source (no inductors, or resistors in series with the source), do you use the average or the rms functions? i.e.: average(IT('/V0')) or rms(IT('/V0'))? Shouldn't they give the same results?
If there is ideal voltage source and load is connected to it, being the ideal voltage source it can source upto infinite current to the load and the voltage level will not drop. Now coming to non-ideal voltage source or voltage regulator; (...)
