要約(日本語)：Asynchronous A-to-D conversion is widely recognized as an effective technique to enhance the speed of multistep ADCs, such as SAR and cyclic ADCs. However, implementing asynchronous operation is difficult for analog components with built-in amplifiers, like cyclic ADCs, due to the required performance on the amplifiers. In this work, a novel zero-crossing-based amplifier suitable for asynchronous cyclic ADC is proposed, and its effectiveness and feasibility are demonstrated through SPICE simulation results.
