Abstract
Official abstract text for this publication.
A differential amplification circuit includes a first current control unit configured to control driving current in response to a voltage level difference between first input voltage and second input voltage, a second current control unit configured to control the driving current in response to a voltage level difference between the second input voltage independent from temperature and a temperature voltage depending on the temperature, and a signal output unit configured to generate a detection signal in response to the driving current.
