In recent years, sensor technology has become one of the most important and critical items for many sophisticated systems such as various mobile devices, audio/visual and household-electrical appliances, medical and biological equipment, and especially booming robot systems. In these domains sensors must deliver higher performance, be more compact, less expensive, and more reliable, and these requirements grow stronger by the day. Moreover, with the explosive growth in the number of sensors in systems, there is a great demand for sensor low-power consumption and sensor networks. Accordingly, the most effective solution must be sensor digitalization for any and all sensors as a whole. However, many sensors still remain as an analog method. The reason is that conventional types of ADCs are not very appropriate for universal sensor applications. We have therefore developed an all-digital A/D converter TAD (Time A/D converter) with a scalable time-mode method. This paper describes the following: The TAD operation principle and its circuit structure, evaluation results, sensor application examples, and scaling effects and possibilities with 65nm-CMOS TAD. Finally, multi-functionality based on time-mode construction is discussed. |
