Semiconductor Company, a subsidiary of Panasonic, has launched an inertial sensor signal processing IC chip. The compact device measures less than 2x2x2mm.

According to the company, this could be achieved by developing 1.8V 110nm BiCMOS, and letting the surface of the precision analog circuits to be shorn to half its size. The company is now producing this device on a mass scale. The device will minimize the overall size. It will also improve the functions of inertial sensor modules used in products like mobile products and game machines. The chips are placed in a big space inside the module and amplify even faint signals transmitted and change them to electrical signals that rely on the inertial force. The remaining area on the board is taken up by precision analog circuits.
The miniature sensors in turn reduce the level of sensor signals, causing a reduction in low-frequency noise in the amplifier circuit that amplifies the signals. Reduction in noise levels lead to an increase in area with traditional CMOS analog circuits.
