Introduction to FinFET Technology Part III

Introduction to FinFET Technology Part III
by Tom Dillinger on 11-21-2012 at 5:30 pm

The preceding two Semiwiki articles in this thread provided an overview to the FinFET structure and fabrication. The next three articles will discuss some of the unique modeling requirements and design constraints that FinFET’s introduce, compared to planar FET technology.

Due to the complexity of FinFET modeling – … Read More


Why are AMS designers turned off by Behavioral Modeling?

Why are AMS designers turned off by Behavioral Modeling?
by Ian Getreu on 11-11-2012 at 8:10 pm

Analog Mixed-Signal (AMS) behavioral models have not caught on with the AMS designer community. Why? I suspect a significant reason (but certainly not the only one) is the way they are presented.

First, what is AMS behavioral modeling?

I define it as “a set of user-defined equations that decribe the terminal behavior of a component”.… Read More


Smartphone Market Share

Smartphone Market Share
by Paul McLellan on 11-09-2012 at 12:47 pm

The numbers for smartphone sales in Q3 are starting to roll in. These are in units and not yet revenue (let alone profit) numbers although everyone down to Sony is for sure profitable. Samsung is running away with the volume, selling more than Apple, Huawei and Sony put together. One name that is missing is Motorola (Google) which … Read More


Apple and Samsung Take All the Profit

Apple and Samsung Take All the Profit
by Paul McLellan on 10-29-2012 at 4:07 pm

I’ve talked before about how Apple and Samsung make most of the money in the handset business (and also about how Nokia…er…doesn’t). Now there is a report from Canaccord Genuity makes it clear just how much of the profit they make: 106%. And that is down from second quarter when they made 108%.

How can they… Read More


Apple v. Samsung: Mixed Phone Marriages End in Divorce?

Apple v. Samsung: Mixed Phone Marriages End in Divorce?
by Daniel Nenni on 10-28-2012 at 8:10 pm

A funny thing happened at dinner the other night. The SemiWiki blog “8 Things I Hate about My iPhone5” caused quite a discussion. Half the table had Samsung phones and the other half iPhones. It really was more of a religious or political debate versus a rational consumer electronic discussion. An interesting side note, it seems … Read More

Google Datacenter
by Paul McLellan on 10-22-2012 at 5:42 pm

In my blog about Intel’s latest results I linked to an interesting article in Wired about Google’s datacenters.

I happened to be browsing some websites in the Netherlands (actually I don’t speak a word of Dutch, a Dutch friend pointed it out to me) and there is an article showing how the pictures that accompany… Read More

Since going online January 1st, 2011 more than 400,000 unique visitors have landed at www.SemiWiki.com viewing more than 3M pages… Read More


A Brief History of Mobile: Generations 3 and 4

A Brief History of Mobile: Generations 3 and 4
by Paul McLellan on 10-18-2012 at 8:30 pm

The early first generation analog standards all used a technique known as Frequency Division Multiple Access (FDMA). All this means is that each call was assigned its own frequency band in the radio spectrum. Since each band was only allocated to one phone, there was no interference between different calls. When a call finished… Read More


iPhone5 Versus Samsung S3: the Key Question

iPhone5 Versus Samsung S3: the Key Question
by Paul McLellan on 10-18-2012 at 8:29 am

In all the discussion about iPhone versus Samsung, the profit leader and the volume leader in the handset business, there is way too much discussion about boring stuff like how many MIPS the A6 chips has and whether the maps are any good on iPhone (no) and is there enough 28nm capacity for Qualcomm. Boring.

The real question that everyone… Read More

A brief History of Mobile: Generations 1 and 2
by Paul McLellan on 10-14-2012 at 9:00 pm

Mobile is one of the biggest markets for semiconductor, especially if you count not just mobile handsets but also the base-station infrastructure. No technology has ever been adopted so fast and so completely. There are approximately the same number of mobile phone accounts as there are people in the world. A few people have more… Read More
