The proposed implementation, developed with only six current mirrors and two large-valued, programmable active resistors, solves some of the more challenging problems of low frequency filtering. HSPICE simulation results using BSIM3.3 models for a 0.5-µm CMOS technology, are shown. Center frequencies in the range of 12.4 Hz - 33 Hz, total harmonic distortion less than 1 %, and static power consumption of 1.05 mW, were observed. |
