Abstract
This paper reports on a field-programmable analog array (FPAA) for high-frequency continuous-time analog filters. A rapid-prototyping hardware is presented, which implements a unique hexagonal lattice topology of 55 tunable Gm cells for reconfigurable instantiation of Gm-C filters in a 0.13 mum CMOS technology. The typical power dissipation is 70 mW at a 1.2 V supply. The chip structure allows intuitive mapping of Gm-C filter schematics with up to seven independent nodes, immediate download to the hardware, and evaluation on the working prototype. Implementations of first- and second-order low-pass and sixth-order bandpass filters are presented and show the feasibility of the array for frequencies up to the order of one hundred MHz.
