本文介绍一款简单、可重复且高精度的PWM驱动16位DAC设计，涵盖滤波器、OP与误差控制方法... 通过将单个脉冲宽度调制器(PWM)与模拟低通滤波器串接，以实现简单的数模转换器(DAC)，这并不是什么新鲜事了。将最最高有效位2 N PWM输出与最低有效位2 N PWM输出相加 ...

In the past few years, the pitch on digital control of switching regulators has been rising steadily. In a typical analog implementation, a pulse-width-modulated (PWM) switching regulator is built ...
