Pulse-width modulation (PWM) peripherals have enjoyed a long association with microcontrollers and power control, starting with motor control and power conversion. For the most part, these ...

In IC design, the typical approach for generating a pulse width-modulated (PWM) signal from an analog value (such as in the control loop for a switch mode power supply) uses a ramp or triangle wave ...

This article describes a simple technique for using a processors PWM output to produce an analog control voltage that matches the load’s input range, thus maximizing control resolution. Most ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

Spice model makes it easy to design with PWM amplifiersHigh-efficiency PWM amplifiers are displacing linear designs in many applications. You can design a constant-current or a constant-voltage PWM ...
