Abstract
A reference voltage generator may include: a differential amplification circuit including a positive input terminal coupled to a supply voltage to receive a voltage from the supply voltage and a negative input terminal coupled to an output terminal of the differential amplification circuit, the differential amplification circuit structured to perform a reset operation based on the received voltage from the supply voltage during a reset period and amplify a difference between a first initial voltage applied to the positive input terminal and a second initial voltage applied to the negative input terminal during a reference voltage generation period; and first and second voltage storage circuits coupled to the positive input terminal and the negative input terminal, respectively, and structured to store the first initial voltage and the second initial voltage, respectively.
