NOISE REMOVING CIRCUIT AND SIGNAL PROCESSING CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a noise removing circuit capable of being integrated and capable of relaxing an abrupt voltage conversion in signal at closing time of a switch.

SOLUTION: In a noise removing circuit for removing the pulse-based noises by opening and closing a switch 12, a current in proportion to a difference between a potential of an input signal and a potential of a capacitor 14 is generated during a prescribed time Tcc just before the switch 12 is closed, and the potential held by the capacitor 14 is changed to relax the abrupt voltage conversion in signal during the closing time of the switch 12.
