Abstract
A new CMOS current-mode integrator for low-voltage analog integrated circuit design is presented. The proposed current-mode integrator is based on cross-coupled gain-boosting topology. When it is compared with that of the typical current-mirror type current-mode integrator, the proposed current-mode integrator achieves high current gain and unity gain frequency with the same transistor size. As a application circuit of the proposed integrator, we designed the 1.8V 200MHz band current-mode lowpass filter. These are verified by Hspice simulation using $0.18{\mu}m$ CMOS technology.
