A new three axis low power MEMS gyroscope for consumer and industrial applications

摘要

The manuscript reports a new commercially available three axis gyroscope, the Freescale FXAS21002C. The 6.8 mW power consumption is 20% less than the nearest competitor's three axis device while meeting standard consumer device parameters. The three axis gyroscope has two proof masses and an open loop control scheme. The open loop architecture and the discontinuous control scheme contribute to this differentiated power consumption.
