  • Abstract
    This paper presents a fast procedure for the system-level evaluation of noise and distortion in continuous-time Gm-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, Gm-C low-pass filter, realized in a 0.18μm CMOS technology, following the proposed procedure, demonstrates the suitability of the approach.
