Digital Closed-Loop Driving Technique Using the PFD-Based CORDIC Algorithm for a Biaxial Resonant Microaccelerometer

<div>Test results of the zero bias stability with different effective bits of the AD and DA convertors: (a) the resolution change of the AD converter with the effective bits of 16 in the DA convertor; (b) the resolution change of the DA converter with the effective bits of 18 in the AD convertor.</div>
