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 popular ‘free’ method in a buck converter is DCR current sensing. It’s free in the sense that no added cost or power loss is added to the design, but these circuits are notoriously inaccurate, particularly when small, low-ESR inductors are used.
