Re: capacitors
In practical applications, normally you would want a big enough capacitor (like 100uF) at the power pins. This acts as a bucket for any switching in the board. It's response is slow though. When the board needs current (charge), the capacitor will supply them before being...
Is there a way to plot simulated data and data from a table on the frequency domain plot? I want to compare simulated results of the transfer function against the transfer function given by the datasheet.
I know that for voltage and currents in the time domain, we can define the data using the...
Re: Sensor output --- voltage output or 4-20mA output is bet
Current output is good if it has to travel through a long cable before being process. There isn't any voltage drop associated with currents along the cable.
If you send through voltage, you will have to deal with voltage drops and it...
Hi,
How do you go about implementing a voltage controlled current source? The symbol for this in Pspice is G.
My inputs are differential (can be positive and negative) and I want the output current to be bi-directional. I cannot ground the inputs or load it.
Thanks.
vov voltage
Vdssat is when it reaches pinch off at the channel. Vgs-Vt is just the potential needed at the gate to inverse the channel under the oxide. This is usually a function of the doping under the oxide and substrate potential.
For short channel, you have a much earlier Vov compared to...
the size of the mos can be different too. the first set of cmos can be smaller than the 2nd set. It gives better driving capability.
You can think of a Not gate as a negative buffer.
Well this argument can go round and round. We can say that cars are pumping out polution into the air, and we breathe it every second. How's that for a reality check? The benefit of having something that destroys us long term is just to great to let it go.
But using an earpiece is a great...
Normally I put my traces as wide as possible for the power lines. Usually 100 mils if possible. When it branches into the circuit area, I use thinner traces like 20 or 30mils.
You can change the units by pressing 'q' from mils to millimeters and vice versa.
To set ground planes, you click on...
I think it is a very hard thing to prove. They will need massive data and long period of time to prove it. Just like smoking and drinking. They can corelate i guess.
However, if you think of it, we are constantly inside electromagnetic field. If you really want to be safe, you will have to hide...
Other types of semiconductors other than silicon have been used for a long time. Some was manufactured even before silicon.
Reason why silicon was popular is because it is easily available and it's oxide is a good stable non-conducting material.
Do search on Germanium (Ge), and Gallium...
It is always good practice to separate them and have them join at one point. Becareful the motor driver, as they tend to draw spike currents which could be distruptive to your grounds. Heavily bypass that power line too. Capacitor values ranging from 47uF to 0.01uF are good.
relationship between snr and ber
They are also use as a standard in communication protocols. For example, if you have bluetooth, you need to have a minimum amount of SNR and achieve the BER in your equipment for it to be certified.
They are related but not necessarily the same. SNR is the...
Assuming that you want to divide by the number 1024, you change your value to binary. Then shift them to the right 10 times. That will give you the desired 1024 division. Remainders will be lost.
For example, if you have 10000, and want to divide by 1024,
0010 0111 0001 0000.
shift...
