Summary:In this paper, a current-mode integrator for low-voltage, low-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 $0.18{\mu}m$ CMOS parameter is performed and achieved 44.9dB gain, 15.7MHz 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 2.12MHz cutoff frequency which is suitable for WCDMA baseband block.
