IDT introduced its first wireless charging products— an integrated
IDTP9030 transmitter and multi-mode IDTP9020 receiver— earlier this year
based on the Qi standard supporting magnetic induction. IDT’s
development of an integrated transmitter and receiver chip set for
Intel’s wireless approach is based on resonance technology. The solution
will enable, for instance, smartphones to wirelessly charge by placing
it next to a PC equipped with the appropriate software. Intel’s wireless
technology supports Windows 7 and 8, according to Naghavi.
induction charging technology employs one coil inside a map and one
inside the receiver. Once the transmitter is placed on top, it would
transfer the energy from the transmitter to the receiver. The difference
between magnetic resonance and magnetic induction technology is there
isn’t a need for a map. As long as the device is close to coil, it will
transfer the power, Naghavi explained.
IDT’s first wireless
charging product “helped us prove our competency in technology to Intel
and others that we have a differentiated solution, and we are able to
integrate these components. Our closest competitor has a multichip
solution,” Naghavi said.
Added Ohr: “IDT should be congratulated
for being recognized by Intel on this.” However, analysts couldn’t
quantify the value of the design win since the wireless charging market
is still in its infancy. Also, product revenues are likely to take five
years to aggregate, according to analysts.
Intel didn’t disclose
when it expects to roll out the reference designs. Meanwhile, IDT
expects samples of a resonance receiver IC to be ready by the end of the
year, and the transmitter IC is expected to sample in the first half of
There are 150 engineering schools in the state of Kerala with graduates leaving India for the allure of companies elsewhere in the world. The state of Kerala wants to keep these engineers right there in this region where they have graduated and is trying to create a “Silicon Valley” in India.
For decades, electronics product innovation has been incremental in nature, relying largely on the next generation of semiconductors to deliver performance improvement. For almost 50 years Moore’s Law has delivered 2x performance (power or cost) improvement in semiconductors every 18 months, outpacing any product or system level innovation cycle that could be achieved by even the most ambitious hardware teams. What has evolved is a “sit & wait” approach, to product innovation. However it is now clear that Moore’s law is broken, and the implications are profound for hardware designers.
You’re in a small company that needs to turn a product quick. Nobody in the company has any power supply design experience yet you need to drive LEDs from a universal (US and European) wall input voltage. What do you do?
