Title: Chattering-prevention circuit for fg signal
Inventor: YOSHITOMI TETSUYA
IPC: H02P6/06
Filed: 2000-06-20
Abstract: PROBLEM TO BE SOLVED: To prevent a chattering to occur when a zero-cross point of a Hall element, i.e., a FG output signal, is switched from a low level to high, or from high to low. SOLUTION: A Hall output signal taken out of a Hall element is converted to a comparator-output signal of a rectangle-wave shape by a comparator, the converted comparator-output signal is formed into a high-low symmetric rectangle-wave signal by a binary-distribution circuit, and a variation of the retardation rectangle-wave signal of each other side is inhibited a little while by the retardation rectangle-wave signal that could have retarded the symmetric rectangle-wave signal. Thereby, the chattering that occurs upon the variation of the retardation rectangle-wave signal is prevented.
