Paper Abstract

A high-precision measure scheme for half-wave voltage V(pi ) of Y-tap MIOC is proposed. This scheme is based on Sagnac interferometer and a saw-tooth wave with special period is used. With this scheme, the temperature characteristics of V(pi ) of a type of MIOC is studied experimentally. The result shows that its half-wave voltage is temperature-dependent. In the range of -10 to +55, the varying value is 0.162V, the temperature coefficient is 662 PPM/degrees C and the variation is linear and repetitive. Experimental study and detail discussion demonstrate that high accuracy can be achieved with this scheme and it is very suitable to be used in studying and calibrating V(pi ) of the modulator used in close-loop FOG in-site.
