Many embedded-microcontroller applications require generation of analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM signals for generating the required ...

Low-cost, 8-bit, single-chip microcontrollers are stingy when it comes to on-chip PWM (pulse-width-modulation) resources. The use of a PWM resource often forces a designer to sacrifice a ...

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 ...

We love little tricks like this. Suppose that you want to generate an IR remote’s signal. It’s easy, because most of the codes are known. But it can be slightly harder because most IR remotes and ...

This circuit transforms a pulse-width-modulation (PWM) signal into non-overlapping clock signals, whose number depends on the length of a shift register. These clock signals can be used to power up ...
