摘要

本文提出了一种新型偏移消除（OC）技术，利用差分对电荷捕获晶体管（CTT）来消除偏移电压（VOS）。在 TSMC 22 纳米技术中，对编程 CTT 的阈值电压（Vth）衰减进行了表征和建模。利用 CTT 的 Vth 退化模型，提出了一种异步编程方案，在差分对 CTT 的每次编程 (PRG) 操作中，根据差分 Vth（$\Delta $ Vth）选择性地对其中一个 CTT 进行编程。实验表明，基于差分对 CTT 和异步编程方案，$\Delta $ Vth 有效地降低到 1mV 以下，并在 27°C 和 85°C 温度下显示出可忽略的保持损耗。

An Offset-Cancellation Technique Using Charge-Trap Transistors and Asynchronous Programming Scheme

In this brief, a novel offset-cancellation (OC) technique is proposed, utilizing differential pair Charge-Trap Transistors (CTTs) to cancel offset voltage (VOS). The threshold voltage (Vth) degradation of programmed CTTs is characterized and modeled in TSMC 22-nm technology. By utilizing the Vth degradation model of CTTs, an asynchronous programming scheme is proposed to selectively program one of the CTTs based on the differential Vth (

$\Delta $

Vth) in each programming (PRG) operation of the differential pair CTTs. The experiment shows that the

$\Delta $

Vth effectively reduces to less than 1mV, and displays negligible retention loss at 27°C and 85°C based on the differential pair CTTs and asynchronous programming scheme.
