    The nice thing about webinars is that if you register for the live one and you can't attend you will still get first notice when the replay goes up. The other nice thing is that you can read a blog review of a webinar or whitepaper on SemiWiki first to see if it is worth your time. If you do attend ...

    Metal fill requirements for inductors are now a fact of life. Fill has long been seen as detrimental to device performance due to parasitic capacitance. The necessity of fill arises from the need to ensure planarization of dielectric layers by using chemical mechanical polishing. Without adequate fill, areas of the chip can ...

    One of the perks of blogging here is being able to get a press invitation to lots of events, often in interesting locations I never even knew existed. Tonight it was a Broadcom event in SPUR here in San Francisco. The ...

    Most analog designers are aware of loops stability. In most cases, stability is understood as AC stability, the goal is ensuring enough phase (gain) margin so as to avoid the loop to enter oscillation. But prior to studying AC stability, DC stability should be questioned. What is that DC stability only few people think of?

    Raising four children is no easy task, believe me. My beautiful wife and I always felt it was important to foster the charitable side of our children by volunteering at the food bank, cleaning up local waterways, and other activities we could do as a family. To be clear, that is why my family did the ALS Ice Bucket ...

    Design engineers frequently struggle with transmission line design and modeling. We can define a length of interconnect that contains more than 1/100th of a wavelength as a transmission line. This seems to be the breakpoint where distributed effects to start to become significant. To improve circuit performance these long runs are usually shielded and drawn on silicon as differential pairs. Transmission ...

    There has been a lot written on this topic, and some expensive tools proposed to solve this issue, but it is still a concern and a mystery for many designers. The point is that whatever efforts you do, the substrate is common to an entire chip and can cause some undesired coupling if not managed properly and at an early stage. As a start point, we can state that any block in a chip can inject current in the substrate, either through capacitive coupling ...

    In case you have not heard, the Ice Bucket Challenge is a social media program aiming to increase the awareness of ALS (Amyotrophic lateral sclerosis AKA Lou Gehrig’s Disease). One of our neighbors recently passed away as a result of ALS so ...

    Yes, verification technologies are open to innovation for improved productivity and performance in the face of ever growing SoC/IP design sizes and complexities. There is not much scope left in processor speed to improve, other than multi-core processors in servers which again need ...

    Often I have been asked by students, researchers and buddying young entrepreneurs about sources of funds for new technology development and innovation. When I came across this wonderful opportunity which has a global appeal, I couldn’t resist myself bringing it to the notice ...
