摘要：
This paper presents a fast procedure for the system-levcl evaluation of noise and distortion in continuous-time G(m)-C filters. The presented approach is based on Volterra's series expansion and matrix algebra manipulation. This procedure has been integrated in a constrained optimization routine to improve the dynamic range of filters while keeping the area and power consumption at a minimum. A seventh-order, elliptic, G(m)-C low-pass filter, realized in a 0.18 mu m CMOS technology, following the proposed procedure, demonstrates the suitability of the approach.
