A CMOS current operational amplifier with constant closed-loop bandwidth properties and high linearity is described and analyzed. A low-voltage architecture is proposed and designed using a 0.3-Cm process. The circuit operates under a 2- V supply and dissipates 130 VW, while exhibiting a closed-loop bandwidth of about 2 MHz using a fixed 100-kOmega feedback resistor.
