Patent ID: 11881270
Assignee: KIOXIA CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A detection circuit comprising:
a first filter circuit configured to output a first voltage based on a first signal;
a ramp circuit configured to output a ramp voltage;
a comparator configured to output a first result of comparison between the first voltage and the ramp voltage and a second result of comparison between a second voltage and the ramp voltage; and
a controller, wherein
the controller determines, based on the first comparison result, a first period of time between a time when an output of the ramp voltage is started and a time when a magnitude correlation between the first voltage and the ramp voltage is inverted, and determines, based on the second comparison result, a second period of time between a time when an output of the ramp voltage is started and a time when a magnitude correlation between the second voltage and the ramp voltage is inverted.
