Title:
Oscillating circuit
Document Type and Number:
Japanese Patent JP5920170
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an oscillation circuit using a comparison circuit which implements a simpler configuration capable of suppressing a variation in oscillation frequency due to a variation in delay time in the comparison circuit.SOLUTION: An oscillation circuit 1 includes a switching control circuit 8 for selecting either of a first capacitor C1 and a second capacitor C2 to be charged by a constant current source 15 and the other to be discharged on the basis of signals output from a first comparison circuit 11 and a second comparison circuit 13. A correction section 4 generates correction data used to correct a first threshold and a second threshold set by a threshold setting circuit 20 on the basis of a charge voltage of at least either of the first capacitor C1 and the second capacitor C2 at a predetermined timing based on the switching timing of the switching control circuit 8.
