Panasonic Corporation has developed technologies to reduce
performance errors and maximize the transistor performance in chips
for multi-gigabit wireless utilizing the 60GHz wireless band, which
is expected to be the future of high-speed wireless communication.
The transceiver LSI also features an integrated miniaturized module
including an antenna, which contributes to the realization of
stable high speed wireless communication for mobile devices.
The chipset incorporates built-in self-calibration to compensate
for performance errors, improving the modulation accuracy more than
1.5 times. This makes it possible to reduce the circuit design
margin, leading to the improvement of the stability of wireless
communications with less than 1W power consumption. By integrating
the transceiver LSI into the miniaturized module, the chipset can
be implemented in mobile devices, enabling the easy exchange of the
rich content, such as high definition videos, among mobile devices
wirelessly.
The developed technology has the following features.
- Incorporates built-in self-calibration
to compensate for performance errors in millimeter wave wireless
circuits.
- Employs signal processing circuits
which equalize the distorted received signal with more than 50%
power reduction compared to the conventional approach.
- Integrates the transceiver LSI in the
miniaturized module including the transmit antenna and the receive
antenna (size: 10mm x 10mm).
This development is based on the following new technologies.
- Built-in self-calibration for the
transmitter and the receiver which reuses existing circuit blocks
to minimize the chip area.
- Unique low power frequency domain
equalizer which significantly reduces circuit size by using a newly
proposed signal processing algorithm.
Panasonic holds 48 Japanese patents and 46 overseas patents,
including pending applications, for this development.
This result was supported in part by the "research and
development project for expansion of radio spectrum resources" of
The Ministry of Internal Affairs and Communications, Japan. A part
of this release has been presented at IEEE International
Solid-State Circuits Conference 2013 at San Francisco on February
20th. Fast File Transfer Demo has also been given at Industrial
Demo Session at the conference on the same day.
