Abstract
There is provided a high resolution circuit for converting a capacitance-to-time deviation including a capacitance deviation detecting unit generating two detection signals having a phase difference corresponding to variations of capacitance of an micro electro mechanical system (MEMS) sensor; a capacitance deviation amplifying unit dividing frequencies of the two detection signals to amplify the phase difference corresponding to the capacitance deviation; and a time signal generating unit generating a time signal having a pulse width corresponding to the amplified phase difference.
