介绍了一种应用于DC-DC转换器的6位自时钟跟踪ADC。根据输入信号的特性，自适应控制机制自动增加或降低自时钟频率，以匹配跟踪和能效。本文设计的模数转换器具有高达50ms/S的转换速率和2.6pJ/转换步长。该模数转换器采用130nm6M1P工艺，芯片面积仅为400×200μm2。在不使用昂贵放大器的情况下，在电源电压为1.4V时，当工作在50 MS/S时，最大功耗为84μW。
A 6-bit self-clocked tracking ADC for the application in DC-DC converters is presented. Depending on the characteristics of the input signal, the adaptive control mechanism automatically increases or decreases the self-clocked frequency to match the tracking and energy efficiency. The ADC described in this paper has a high conversion rate of up to 50 MS/s with 2.6 pJ/conversion-step. The prototype ADC occupies a very small chip area of 400×200 μm2 on a 130 nm 6M1P technology. Without using costly amplifiers, the maximum power dissipation is 84 μW at a supply voltage of 1.4 V when operated at 50 MS/s.
