【Abstract】 This paper desins and studies a new low-voltage, low-power, constant transconduc-tance rail-to-rail CMOS op-amp. Input circuit uses a new current mirrors technology and outputcircuit is push-pll. In a word, the swing of the whole circuit is rail-to-rail. The circuit designis realized in 0.35 m CMOS technology and works in a 2.0V low supply voltage.更多还原
