In this paper, a new low-voltage continuous-time current comparator is presented. The main idea is to use the flipped voltage follower as a key element for the comparator input stage. This configuration delivers a very low input resistance, which is mandatory for current-mode applications. Previous reported current comparators present a high-speed response; nevertheless, only few are suitable for low-voltage applications. Simulations and experimental results of a fabricated prototype using the complementary MOS 0.35-μm technology are presented to demonstrate the circuit feasibility.

基于 FVF 的低输入电阻 CMOS 电流比较器，适用于低功耗应用

在本文中，提出了一种新的低压连续时间电流比较器。主要思想是使用翻转电压跟随器作为比较器输入级的关键元件。这种配置提供了非常低的输入电阻，这是电流模式应用所必需的。先前报道的电流比较器呈现高速响应；然而，只有少数适​​用于低压应用。展示了使用互补 MOS 0.35-μm 技术制造的原型的模拟和实验结果，以证明电路的可行性。
