摘要：
The design of a Gm-C complex filter for low-IF WPAN applications is described. Sixth-order complex Butterworth filter is designed using a simple architecture of the transconductance in the desired Gm-C filter. This new structure makes the filter suitable for high frequency applications with proper dynamic range, lower power, and minimum Die area. Simulation results show that the filter provides more than 55 dB image rejection ratio (IIR) and IM3 of -50 dB for 1.9 & 2.1 MHz signals with 0.2Vpp. The complete filter including on-chip tuning circuit consumes only 0.4 mA with 1.8 V single supply voltage.
