Improved Pwm Circuit

Pulse width modulation (PWM) is a common technique for generating analog voltages from a digital device such as a microcontroller or FPGA. Most microcontrollers have dedicated PWM generation peripherals built in, and it only takes a few lines of RTL code to generate a PWM

A pulse-width modulated (PWM) circuit applies voltage to a load with high fidelity. The circuit includes switches (Q1, Q2) connected in series with inductors (L3, L4), the inductors being magnetically coupled to other inductors (L1, L2) connected to the gates of the switches. The arrangement of inductors and the magnetic coupling causes the turn-on of one switch to assist in the turn-off of ...
