摘要

基于稳定时间对一般的单极、双极和三极运算跨导放大器（OTA）进行了分析。开环频率响应的最重要的设计指标，如稳定裕度和增益带宽乘积（GBW），与闭环配置中的单级、两级和三级OTA的稳定时间有关，从而能够基于稳定时间规范为每个OTA提供设计过程。为每种情况提供了晶体管级设计示例，以验证所描述的基于沉降的设计策略。

Analysis and Design Procedures of CMOS OTAs Based on Settling Time

Analysis of generic single-pole, two-pole, and three-pole operational transconductance amplifiers (OTAs) is carried out based on settling time. The most important design metrics of the open-loop frequency response, such as the stability margins and the gain-bandwidth product (GBW) are related to the settling time of single-, two- and three-stage OTAs in closed-loop configuration, enabling to present a design procedure for each OTA based on the settling time specifications. Transistor-level design examples are provided for each case to validate the described settling-based design strategies.

期刊介绍： This journal will present state-of-art papers on Integrated Circuits and Systems. It is an effort of both Brazilian Microelectronics Society - SBMicro and Brazilian Computer Society - SBC to create a new scientific journal covering Process and Materials, Device and Characterization, Design, Test and CAD of Integrated Circuits and Systems. The Journal of Integrated Circuits and Systems is published through Special Issues on subjects to be defined by the Editorial Board. Special issues will publish selected papers from both Brazilian Societies annual conferences, SBCCI - Symposium on Integrated Circuits and Systems and SBMicro - Symposium on Microelectronics Technology and Devices.
