Introduction In my previous post, I talked about the design of a simple 25 Mbps transmitter with PRBS generator, encoding and pre-emphasis. I designed the circuit using the discrete logic components in order to get a better understanding of modern transceiver circuits. Since the standard (25 Gbps and higher) transceivers are implemented in the silicon … Continue reading 25 Mbps discrete logic transceiver – TX prototype debugging
Introduction Yes, new year is here and it’s a perfect time to get to this blog back again. For this post I decided to look back at some social aspects of my engineer’s year. New Job As of end of 2017 I joined a new company – IMS Nanofabrication. It’s an Austria based semiconductor fab … Continue reading A Year in a Review
Introduction During my time as a PhD student, I had an opportunity to work in the laboratory of ceramic technologies. I got to produce various electronic components based on so-called low temperature co-fired ceramics, or LTCC. Although it’s been more than 2 years since I left that lab, I found some time to reflect back … Continue reading Building a Circulator out of Ceramics
Introduction Having my reflow solder oven finished, I couldn’t wait to see how far can I challenge it with complex circuit boards and tiny components. I decided to build a system with components that are tricky to solder, such as BGA and QFN packages. Not interested in designing the whole circuit on my own, I … Continue reading Building an ARM based microcomputer at home
Introduction I’ve been trying to sort out all those computer memories in some meaningful order in my head for some time and it turned out to be not an easy job. Partly because of my head and partly because of all the various memory types out there: volatile, non-volatile, read-only, RAM, DRAM, SDRAM, permanent, Flash…does … Continue reading Remember the memories
Introduction The coolest sounding theory in modern science is definitely the Chaos theory. No one is quite sure what it stands for, but we like to use the phrase to say that something is messy and there is no convenient way to describe it. And butterfly, there is always that butterfly whose wings can cause … Continue reading Chua’s Circuit – Chaos in its most simple form
