LONDON – The market for mobile handset ICs, including platform and connectivity ICs, was about $32.2 billion in 2011 and is forecast to grow 11 percent in 2012 to reach $35.7 billion, according to market research firm ABI Research.
Qualcomm was the leading supplier of mobile ICs in 2011 with 26 percent, ABI said. The company expects Qualcomm to lead again in 2012 but did not give a market share estimate for 2012.
Rival analyst Strategy Analytics recently estimated Qualcomm's market share at 48 percent in the first half of 2012.

MediaTek is following hot on Qualcomm’s heels with its MT6575 platform for low- to mid-end smartphones and is changing from a lower-end handset to a smartphone-focused supplier. Broadcom continues to lead the handset wireless connectivity market with almost 40 percent revenue market share, due largely to its strength in the combo IC market.
Qualcomm, Broadcom, Texas Instruments, and MediaTek are strong in both platform ICs and connectivity ICs
"For all handset IC suppliers their future fortunes in the market will be bound by their ability to embrace integration and supply the market with compelling solutions that enable high functionality whilst keeping costs down," said Peter Cooney, director of semiconductors, at ABI Research, in a statement.
A few years ago, I was working on the design of a data acquisition system (DAS) that would eventually need to be tested when manufactured. It had both high-side current sensing and floating diff-amp input channels. I could either recommend to the client that some expensive equipment be bought and configured for such testing or else design and build some prototypes of a Floating Differential Source (FDS) which would cost much less. I did the latter.
As an engineer, eventually you will have to insert an equation into your written work or presentation. This can be a struggle as equation editors are not always the friendliest. However, there is good news. The equation editor in Word has improved immensely (I am using version 2010 here). In this blog we look at how to insert an equation into a Word document. As a bonus, there is information on how to insert an equation into a web page with an html code generator website.
Wait a minute. Let’s see if I understand this. (Here I’m channeling you, the puzzled reader, after you’ve grabbed me in the coffee break of a Filter Wizard lecture morning). The frequency of the nth harmonic of a sinusoid is n times that of the fundamental. The nth harmonic distortion is defined as the ratio of the amplitude of the nth harmonic to the amplitude of the fundamental. So the 1st harmonic distortion is… the ratio of the amplitude of the fundamental to the amplitude of the fundamental and that’s… unity. I. Do. Not. Understand.
