Abstract :
A completely programmable and reconfigurable digitally controllable active structure is presented. A specific implementation, which has over three decades of adjustment range and is capable of realizing any even-order filter function of up to sixth-order, was fabricated and tested. The filter operates over the 1-kHz to 1-MHz frequency range. Experimental results that confirm the reconfigurability and programmable characteristics of this structure are presented
