1. A system to improve a start time of a MEMS gyroscope, comprising in combination:
drive electronics connected to a MEMS gyroscope, wherein the drive electronics includes at least one amplifier; and
a bias power source connected to the drive electronics, wherein the bias power source provides a substantially continuous source of voltage to The drive electronics when a system power source is not applying power to The MEMS gyroscope, wherein the substantially continuous source of voltage prevents the at least one amplifier from saturating when the system power source is applied to the MEMS gyroscope.
