Hello Everyone, I want Arduino code for complementary dead time PWM. Can anyone have please Send it
I don't get why you have the rnd signal set to be 10-bits it only has 8 states so only needs 3-bits. I would get rid of the inversion of the LED_status assignments and just assign a 1'b1 to the selected LED_status and add a LED_status <= 8'b0 just before the case to ensure each time you have 5,000,002 clock cycles yo
Ok fair but consider the same thing is true for any mosfet yet we parallel them all the time with the expectation of better than 2:1 sharing. Steep Rdson thermal gradients are one reason this works. When a manufacturer says you can do something you usually can. I'm building a board right now that's expecting to parallel Vicor modules.... You do
Hi, I am looking for a converter to transfer the mechnical energy from bicycling pedal to the electrical energy. Here is the application: 1. the tire of the bicycle can move ahead around 1 meter per second, that is the input of the mechnical energy 2. I am trying to charge a battery that is 3V and 500mAhr capacity. That is where the output ele
In the data sheet of a 400 MHz transistor I found fall time = 60 ns. Clearly these are contradictory specifications - trise and tfall should be at least an order of magnitude shorter. Should I believe that fT is specified correctly? (e.g. 2SA2088FRAT106Q transistor).
If you're of an experimental mood, you can use input or output ESD diodes, or possibly active pin attributes as a temperature proxy; a little oven time and some data points for diode Vf@If, and you've got yourself a regressable temp function. Need to stay away from imposed high power which could create gradients on the die and in the package, an
What simulator do you use ? Show me netlist fragments regarding analysis and option settings. Hi, Attached you can find the netlist, which is a ring oscilator. The option settings for the transient analysis in ADEL Cadence. And the data generated when downloaded in .CSV file. Is important to say that this amou
Hello, I am currently doing my project which requires me to use DE1-SoC. The project is to perform bearing health?s prognostic, it includes 3 parts which are: feature extraction, linear regression, and remaining useful life estimation using polynomial regression. What I have is the Python code for the above 3 functions, and I want to perform fe
I have PIC16F886 4mhz crystal 1ms timer interrupt.I have code working as below. Now currently facing updating ms and Sec parameter. the min and sec parameter will update properly but not in msec and sec void interrupt isr(void) { asm("clrwdt"); if (TMR1IF) { TMR1IF = 0; // TMR1H = 0x3C; // TMR1L
You have to apply modulated signal for evaluation of ACLR, use envelope analysis which is time variable HB.
I need to measure the relative phase of two sinusoids (around 2-2.2MHz. Both signal are always of identical frequency) using an FPGA. Both signals are sampled with an ADC at 40Msps. Everything about those two signals is synchronous to that sampling clock. Getting a phase measurement which is both accurate (like <5 degrees) and also gives unique res
1/2 sample period is no meaningful quantity in sampled data system. Output is only observed at integer multiples of sampling period. You'll see if you cascade two of the shown stages. What's the total time delay?
Hello All, I would like to know how the mobile knows which frequency(2G/3G/4G) it is using while communicating? for e.g. when i am moving, sometimes mobile shows it is in 3G network and sometimes in 4G Network. so i want to know when mobile network switch from 3G to 4G or vice versa, what really happens inside the mobile (hardware level)?
Hi all, I have requirement for a display PCBA, It has some 7-seg LEDs display (used for home appliance). I met a problem: after a certain time, one or several segments were broken and no light. (error rate about 0.5%) To solve this trouble, our supplier (an IDH) who designed my PCBA said he must design the new 7-seg LED with integrated Zener dio
I need to build a circuit that should save power of the "next" (main) stage for 12 hours. So the 12 hours is the duty cycle. I've run into TI nano timers but their max duty cycle is just 2 hours. And I need 12. Also, I'd like to be able to set the "reference point" with a button click or some "pre-
The 150 ohm resistance is always in the path between the op amps, thus it is the ohmic portion of the load. As for capacitors, they present zero resistance for a brief time after a change in current flow. The definition of capacitance is that it impedes a change in voltage. An op amp output has internal resistance. There may be a certain value of
I used simple formula not huge coding needed but unfortunately no one in thread could provide proper answer, however problem solved Problem 'solved' with a bad programming style, consider next time using state machine handling delays with flags instead of closed loop delays. I would not be surprised if you reopen the discussion re
157779 I'm having very hard time writing code for pic16f877a for my solar powered multilevel inverter with the above switching strategy. Can someone help me write this code? PLEASEEEE...:idea:
MSO2000B series has 1M data points memory, about 10 sec @ 100 kSPS. timebase can be set up to 100 s/div, 1000 s total length with respective lower time resolution. Not sure if quasi continuous data transfer in roll mode is supported by the oscilloscope.
I am using PIC16F886 4mhz crystal timer1 interrupt with 1ms . i am trying to build timer application. When top display == bottom display the process should stop. Top display Set value Bottom Display shows process value. Top display set usually in time format if value 0210 means if LED_SS==0 02Sec 10ms LED_MS==0 02Min 10S LED_HM==0 02H
