+[* black] Chipworks has confirmed that the MEMS gyroscope found inside the iPhone 4 is nearly identical to an off-the-shelf STMicroelectronics [link|http://www.st.com/stonline/products/families/sensors/l3g4200d.htm|L3G4200D] gyroscope.
+[* black] The picture of the die you see on the left is that of the GK10A MEMS die, found in the L3G4200D.
+[* black] The GK10A is comprised of a plate that vibrates when a drive signal is applied to set of drive capacitor plates.
+[* black] When a user rotates the phone, the vibrating plate gets displaced in the X, Y, and Z directions. An ASIC processor senses the plate's displacement through capacitor plates under the plate, as well as finger capacitors at the edges of the package.
