A Low Power Dynamic Circuit Topology towards a-IGZO Thin-Film Ultrasonic Transducer Driving Circuit
2021 IEEE International Conference on Flexible and Printable Sensors and Systems (FLEPS)（2021）
摘要
A 4bit counter with dynamic logic is demonstrated running up to 3.5MHz at 8.4V using amorphous indium-gallium-zinc-oxide thin-film transistors (a-IGZO TFT). Dynamic logic is selected to achieve the required speed for digital circuits driving ultrasonic transducers enabling large-area ultrasonic applications. In addition a back-gate switching technique is introduced in order to further reduce logic...
