ABSTRACT:
A differential amplifying device includes a first differential amplifying unit that receives an input signal and a reference voltage. The first differential amplifying unit amplifies the input signal to generate an output signal when a sensing signal is at a first level. A second differential amplifying unit is configured to also receive the input signal and the reference voltage. The second differential amplifying unit amplifies the input signal to generate the output signal when the sensing signal is at a second level. The first and second differential amplifying units are configured to take advantage of transistor characteristics.
