Abstract

PWM signal source are quite common now. Many people know their principle, but less people know how works this mechanism in fact. Signal source PWM is available in integrated form. But work trying to solve implementation by discrete devices and operational amplifiers. This method is difficult, but emphasis on understanding the principles and processes. And it is not only in alone source but too in his partial block and devices. Work trying to solve only general thing. For example comparator function, structural problems as blocking source contacts by block capacitor. It is complete design and implementation of PWM signal source and on this end is finished product.
