What is a PWM Generator?
A
PWM generator (Pulse Width Modulation) is an electronic device or circuit that generates a sequence of pulse signals with varying
duty cycles. These pulses can be used to control power delivery to various devices, including motors, LEDs, and other electronics. In the context of
nanotechnology, PWM generators play a crucial role in controlling nanoscale devices and systems.
How Does PWM Work in Nanotechnology?
PWM works by switching the power supply on and off rapidly, adjusting the duration of the "on" time relative to the "off" time. This ratio is known as the duty cycle. By manipulating the duty cycle, PWM can effectively control the power delivered to a device. In nanotechnology, this precise control is essential for
nanoelectronics and other nanoscale applications where exact power regulation is required.
