Abstract :
A complete automated development system for up to 16th-order semicustom switched-capacitor (SC) filters is presented. A unique synthesis and design methodology is used which leads to simple and regular SC structures that are defined by a single unique metal layer on a CMOS gate-array-type filter chip. Two high-order ladder filters and a cascaded biquad filter have been designed and implemented with this technique. Experimental results indicate that performance comparable to full-custom implementations can be achieved.<>
