That was my mistake sorry.
I can definitely change some of the requirements. Storing captured data to high speed RAM was the first thing that came to my mind because many oscillscopes work that way. Is it easier to use high-speed USB at this data rate?
Your data rate is higher. It's more than...
Thanks for all of your responses.
The first problem that I wanted to solve was getting data from ADC to RAM at the desired sampling rate.
I didn't think implementing usb in FPGA is going to be such a problem. It seems like a microcontroller with appropriate usb controller would make things...
It's going to be sent to the computer via USB for analysis and processing.
I want to capture 64Msamples at 20Msample/s. For 14-bits it's 280Mbps. I want to write all of that into SDRAM (SDR SDRAM) and send them to the computer via USB when the acquisition is done. It's basically a DAQ system...
I am trying to find the best way to interface with this ADC https://www.ti.com/lit/ds/symlink/adc14l020.pdf
I am new to this subject (obviously), I dealt with analog stuff mostly. That's why I am here ask for advice
It is a 20 MSPS 14-bit ADC with parallel interface.I want to store 64M samples...
I got solid copper plane in layer 2 as you said. As for my 4th layer (bottom layer). I got almost no trace. My question is should I just turn it to another another ground plane?
Hello,
I'm designing a 4-layer PCB and I finally finished routing, but I am kind of confused about a grounding of the last layer in my PCB.
I went with a very conventional stack-up:
1-layer - signal routing
2-layer - GND
3- layer - PWR
4- layer - signal routing (almost blank)
I almost only used...
Even the cheapest soldering irons would work with its standart tip actually. I am not saying they are the perfect fit for the job, but if you just want to solder 0402 passives to your PCB you can pretty much any soldering iron.
Matching network should be designed in such way that it converts rectifier's input impedance to the antenna's input impedance so that they are matched.
Try to run harmonic balance analysis and connect current probe at the input. You should convert the input power to voltage and divide it by...
It's referring to the current consumption of the IC itself (Quiescent current) when you disable the converter from its EN (pin - 3). It is no referring to the load.

In that case I assume there is no bias for the rectifier circuit (which is typical). This type of circuit is very nonlinear meaning that its input impedance changes considerably with the available power at the input. For example, when you match your rectifier for -20dBm, the matching network...
