In this paper, a current-mode integrator for low-voltage, lew-power analog integrated circuits is presented. Using the proposed current-mode integrator, the baseband analog filter is designed for WCDMA wireless communication. To verify the proposed current-mode integrator circuit, Hspice simulation using 1.8V TSMC 0.18㎛ CMOS parameter is performed and achieved 44.9㏈ gain, 15.7㎒ unity gain frequency. The described 3rd-order current-mode baseband analog filter is composed of the proposed current-mode integrator, and SFG(Signal Flow Graph) method is used to realize the baseband filter. The simulated results show 2.12㎒ cutoff frequency which is suitable for WCDMA baseband block.
