摘要：

This paper presents elliptic low-pass filters based on OTA-C structure for the implementation in the analog front-end (AFE) of biosignal detection systems. Second, third, fourth, and fifth-order filters are proposed, and validated using 90nm CMOS technology in LTspice. The transconductance of the OTA used is analog tuned from 0.155 nA/V to 1.4 nA/V. Equal capacitors of pF capacitance are used in implementation. Magnitude responses of the various filter orders focused on the 50 Hz notch frequency. The fourth, and fifth-order filters provide a choice of single or double notch response.
