摘要

本文提出了一种用于快速响应PWM降压变换器的带有有源斜坡跟踪控制(ARTC)的简单斜坡发生器。它将传统坡道发生器中的两个放大器和两个模拟电平移相器与ARTC简化为一个放大器。与ARTC的传统坡道发电机相比，拟议的坡道发电机的面积和功率分别减少了31%和44%。采用1.8V 65nm CMOS工艺制作了带有斜坡发生器的PWM降压变换器。

A Simple Ramp Generator With an Active Ramp Tracking Control For a Fast Response PWM Buck Converter

In this paper, a simple ramp generator with an active ramp tracking control (ARTC) for a fast response PWM buck converter is proposed. It simplifies two amplifiers and two analog level shifters in the conventional ramp generator with the ARTC to a single amplifier. The area and power of the proposed ramp generator are reduced to 31% and 44% compared to the conventional ramp generator with the ARTC. The PWM buck converter with the proposed ramp generator was fabricated in a 1.8V 65nm CMOS process.
