An angular rate amplifier, which is adapted to amplify useful signals, which are proportional to rotation motion of a carrier, and to suppress noise, which is not proportional to rotation motion of a carrier, in output signals from an angular rate producer, including a MEMS (MicroElectronicMechanicalSystem) angular rate sensor. Compared with a conventional amplifiers, a noise shield and a co-resident trans impedance amplifier are utilized to achieve high signal/noise ratio. Furthermore, the angular rate producer and the noise shield and a co-resident trans impedance amplifier are used in a micro inertial measurement unit (IMU) to improve performance of the micro inertial measurement unit to form highly accurate, digital angular increments, velocity increments, position, velocity, attitude, and heading measurements of a carrier under dynamic environments.
An angular rate amplifier for an angular rate producer having an output pin, comprising a noise shield, wherein said angular rate amplifier and said noise shield are designed on a printed circuit board (PCB) which has a ground plane, wherein said noise shield further comprises:
