Easy to use AD9833 C Library
Hey there, fellow electronics enthusiasts! If you’ve ever tinkered with the signal generation, you’ve likely come across the AD9833 waveform generator chip. But did you know that this little gem can do so much...
Noise Figure measurement with TinySA Ultra
In an article I wrote long time ago, I measured the noise figure of an amplifier using only a spectrum analyzer. The method I used was relatively simple but it took some mathematical understanding...
Using the Signal Integrity tool in Altium Designer – Part 2
In part 1 of the article series, We learnt how to set up our design for performing signal integrity analysis using Altium’s in-built Signal Integrity tool. The process turned out to be quite simple...
Using the Signal Integrity tool in Altium Designer – Part 1
Our designs are becoming faster to serve our ever-growing demands from machines. Speed brings more complexity to the design. The usual slow transitions from 0 to 1 and 1 to 0 become so fast...
Quickly designing a 23cm Hairpin filter in ADS
A 23cm hairpin filter operates around the 1.296GHz amateur radio band. The frequency being low enough allows us to fabricate it on a low cost FR4 substrate. It operates as a bandpass filter. There...
LM2731 boost converter in Altium Designer – From schematic to PCB
In this quick article, I show step by step process of drawing a boost converter schematic and finally ending up with a PCB layout. All of it done on Altium designer using Altium’s own...
Receiving with 2 channels on PlutoSDR
The Analog devices PlutoSDR comes with the AD9361 chip. Meant for learning, the PlutoSDR comes at a much more affordable cost as compared to the USRP. Of course, the USRP has its own advantages...
Seeed Fusion PCB fabrication review 2022
I reviewed JLCPCB PCB fabrication service a few years ago. Since then a lot has changed. There have been stories, both good and bad about JLCPCB. You can read the comments on that post....
Capturing video with Petalinux – Part 1 – The hardware design
In one of the previous articles, I showed you how you could build a basic design on Zynq SoC and boot Petalinux over it. This article would be an extension to the previous one. Our...
