Abstract
We present techniques for accurately characterizing the frequency response and noise spectral density of integrated continuous-time filters. A 75-MHz fifth-order Chebyshev Gm-C ladder filter designed in a 0.35-mum CMOS process and packaged in a 40-pin DIP is used as a test vehicle to validate the ideas proposed in this work. When compared to conventional frequency response measurement methods, the proposed techniques show a significantly enhanced measurement accuracy in the stopband, while being less sensitive to package characteristics.
