A system and method is provided for reducing the sensitivity of the rotation rate measurement to the frequency dependence of the feedback modulator. Specifically, the system and method uses a minimal bias switching technique to reduce rate errors associated with the low frequency 2&#x3c0; resets in a closed loop fiber optic gyroscope with a phase modulator with a different phase shift associated to low and high frequencies. In general, the minimal bias switching technique reduces the low frequency components of the feedback modulation drive by increasing the frequency of the 2&#x3c0; resets. As a consequence, the system and method reduces the low frequency component of the feedback modulator drive to avoid errors that occur with the low frequency 2&#x3c0; resets.
