Abstract

In this paper, a dual mode baseband analog channel selection filter is described which is designed for the Bluetooth and WCDMA wireless communications. Using the presented current-mode integrator, a dual mode channel selection filter is designed. To verify the current-mode integrator circuit, Hspice simulation using 1.8V Hynix $0.18{\mu}m$ standard CMOS technology was performed and achieved $50.0{\sim}4.3dB$ gain, $2.29{\sim}10.3MHz$ unity gain frequency. The described third-order dual mode analog channel selection filter is composed of the current-mode integrator, and used SFG(Signal Flow Graph) method. The simulated results show 0.51, 2.40MHz cutoff frequency which is suitable for the Bluetooth and WCDMA baseband block each.
