摘要： A resolver use angle detection IC subjected to a phase lock operation so as to follow not an angle θ(t) for detection, but a phase angle ωot±θ(t) having an offset of a frequency ωot in the phase lock units. For this reason, when the excitation frequency ωot is set sufficiently high with respect to the frequency of the angle θ(t), the phase angle ωot±θ to be followed in the phase lock units will not become zero. For this reason, an angle having a high precision can be found in real time regardless of the configuration not including the conventional apparatus in which the configuration is complex and the power consumption is large like a bipolar VCO and an up/down type counter.

摘要： It is an object of this invention to provide a digital conversion method for an analog signal in which, when sin(&thgr;−&phgr;) is calculated as a error deviation &egr;, a first output signal sin(&thgr;−&phgr;)·f(t) of the previous stage of the error deviation &egr; is converted into a digital signal by positive/negative sign determination performed by a comparator to make almost circuits into digital circuits, thereby making it easy to form an IC. In the digital conversion method for an analog signal according to the invention, sin(&thgr;−&phgr;)·f(t) obtained by guiding the rotation detection signal to a multiplier and operating the rotation detection signal is converted into a digital signal by positive/negative sign determination performed by a comparator to achieve a stable and inexpensive configuration.
