Abstract

This paper presents a proposed inverter-based triple-tail comparator designed for high-speed and high-efficiency applications in analogue-to-digital converters. In this proposed comparator, auxiliary inverter based pre-amplifier is proposed to maintain the gain of the pre-amplification stage and bolstering the robustness of the pre-amplifier. Combined with offset cancelled technique, the definite state for each prior to comparison eliminates hysteresis effects. Utilizing the 28 nm CMOS process, the comparator achieves a high-speed data conversion rate of 2 GHz and a root mean square offset of 1.5 mV, representing a reduction of over 62% compared to traditional structures.

基于辅助逆变器的高速前置放大器的1.5 mV偏置动态比较器

本文提出了一种基于逆变器的三尾比较器，设计用于高速、高效的模数转换器。在该比较器中，提出了基于辅助逆变器的前置放大器，以保持前置放大级的增益并增强前置放大器的鲁棒性。结合偏移抵消技术，对每一个预先比较的确定状态消除了迟滞效应。利用28纳米CMOS工艺，该比较器实现了2 GHz的高速数据转换速率和1.5 mV的均方根偏移，与传统结构相比降低了62%以上。
