Title:
COMPARATOR, AD CONVERTER, AND RADIO COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/098193
Kind Code:
A1
Abstract:
A comparator of an embodiment comprises a first transistor, a second transistor, an output stage, and a node group. The first transistor is provided in an input stage and operates when first voltage applied thereto exceeds a first threshold value. The second transistor is provided in the input stage and operates when second voltage applied thereto exceeds a second threshold value. The output stage switches and outputs voltage in response to the switching of the magnitude relationship between the first voltage and the second voltage. The node group changes the first threshold voltage and/or the second threshold voltage during non-operation during which the first voltage and the second voltage are not compared.
