Abstract

PURPOSE:To obtain a reference voltage source which forms a constant voltage that can be utilized to the gate input voltage of constant current source Tr for both MOS differential amplifier and arithmetic amplifier by using the difference of the different threshold voltage of same-polarity transistor Tr for the bias current of constant current source Tr.
