ABSTRACT:
To enhance analog to digital conversion performance by obtaining a digital angle output using a negative feedback system including a resolver within a closed loop. The present invention provides a method of converting an analog signal into a digital signal, including inputting a two-phase sinusoidal signal an R/D conversion portion and converting an input rotational angle (θ) into a digital angle output (Φ), in which the method includes obtaining the digital angle output (Φ) using a negative feedback control system including the resolver within a closed loop.
