Abstract :
A systematic method is presented for generation and design of current-mode continuous-time multiple integrator loop all-pole filters using dual output operational transconductance amplifiers and capacitors (DO-OTA-C). A number of architectures including canonical realizations are developed, with particular emphasis on high-order configurations. These current-mode DO-OTA-C filter structures have various interesting advantages
