Abstract
In aspects of the invention, an operational amplifier circuit includes: an N-MOS auxiliary current source connected in parallel to the N-MOS differential pair, the N-MOS auxiliary current source turning ON when the N-MOS differential pair turns OFF caused by a decreased common mode input voltage given to the pair of voltage input terminals, drawing a current from the active load for the P-MOS differential pair. Aspects of the invention also include a P-MOS auxiliary current source connected in parallel to the P-MOS differential pair, the P-MOS auxiliary current source turning ON when the P-MOS differential pair turns OFF caused by an increased common mode input voltage given to the pair of voltage input terminals, delivering a current to the active load for the-N-MOS differential pair.
