演講大綱：
Inertial sensors have been used since the 1950s in aerospace and defense applications primarily for navigation. The size, power, and cost reduction enabled by micromachining and custom electronic interfaces opens many new applications in the automotive and consumer sectors. Extensively used since the 1990s as crash sensors in vehicles, accelerometers and gyroscopes are increasingly used also to detect and restore loss of steering control using individual wheel breaking. More recently consumer applications for gaming and in mobile communication devices are fueling the rapidly expanding market.
We present an unconventional approach to gyro interface electronics that combines resonant gain boosting and sub-kT/C low noise amplification to realize more than an order-of-magnitude power reduction compared to conventional solutions. The device employs positive feedback to ensure robust and stable operation to accommodate over 200 degrees phase shift from parasitic resonances and transport delay. The measured spot noise of the gyro is 14deg/h/rt-Hz in a 50Hz signal band and 1mW power dissipation.
