Hi everyone,
I am having a problem with accumulator code in Verilog. I simply generate pseudo random signals. Then, change the random signal level -1 to 1 from 0 to 1 so it is signed. Later, obtained 'acmin'. In this point, I need to accumulate 'acmin' signals. Debugger doesn't give me any error...
Hi,
I am very confused about Kalman filters,right now. One of my lecturer wants me to estimate room temperature after 5 minutes when air conditioner in that room stops working. So I have a temperature sensor which measures room temperature and a current sensor which tells whether air conditioner...
Hi everyone,
I recently made an arduino sensor shield. However, I realized (before testing) that one of the current sensors can give 90mA output current. Then I checked out the arduino I/O pins and the max current pins can stand is 40mA. So what can I do? I want to decrease this current which...
Hi everyone,
I have 32nm level 54 Nmos model. I want to simulate the change of threshold voltage accroding to channel length in LTspice but I do not know how. When I make dc op, it does not show Vth directly. with linear extrapolation technique, Vth can be found but it does not still show Vth...
Thank you for your answer Mr.Max. I need to ask one more question. I am a little bit confused about the resistances of MOSFET. As I know, Ro=dVDS/dID in both saturation and linear region, just the formula of ID changes. When we try to calculate AC gain, we are using small-signal model where the...
Hi everyone,
In the figure, according to the Mr.Baker's book, if we inject the current to drain, Id increases (I agree with that) so Vds increases since we keep Vgs constant. I agree with that too if we just look at the formula of Id= Idsat+Idsat*lambda*(Vds-Vdsat). However, if ı consider this...
Hi everyone,
I am going to make Arduino sensor shield with 2 current sensors and one temperature sensor. That's why, I need to make double sided PCB by using Altium Designer. Can you suggest or give me a website,video,book,textbook something like this to understand how it is done?
Thank you.
Thank you Klaust, multiplexer is easy and clever solution. The switches are mosfets. I am using timer modules to control them. Frequency of this switches 6KHz duty cycle %53. I meant number of timers, sorry for my fault. As I told you , ı choose one switch and make 50 cycles with that period...
Hi,
with MSP430G2553, I will control 4 switches by using timers. TimerA 1.0 counts and TA1.1 can determine the period for switch1. TA0.0 counts TA0.1 can determine the period for switch2. What can ı do for switch3 and switch4. All duty cyles and frequencies are the same for each switch But no...
Thank you for your answers, Mr.d123. Trust me, I am spending so much time by reading datasheets but it is so hard to understand which parameters are crucial for my design. That is why, I am asking questions. One reason is that, I live in Turkey and I am going to order some ICs from abroad and...
First of all, the behavior of the current is determined according to frequency of the circuit. It is true and I just send it to you see the change of the current. For spesificatıon, ı do not what these spesifactıon in the picture means and how can I choose them properly. You can give a range...
Mr.Klaus, with all my respect, I am newbie at electronic and trying to learn information about electronics so please ignore my mistakes, I am trying do my best. I would want to give all information at once but I could not realize whether this given information is enough or not.
The cells are...
Hi,
I am planning to use FDS6670A N channel power mosfet. In picture IMosfet, you can see the current waveform on the MOSFET. The first question is if I change my circuit and only the amplitude of the current changes, can the mosfet still conduct? For example, the peak of the current could be...
