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 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 ...

In LCD backlight applications, a dc-to-ac inverter drives cold-cathode fluorescent lamps. The inverter's input comes from the display's power supply. Currently, it spans from 12 to 18 V. Pulse-width ...

Pulse-width modulation (PWM) is an efficient method for controlling the light intensity of a lamp or the speed of a simple DC motor. It lets you take advantage of the load's inertia by switching the ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

Fujitsu Laboratories has developed a CMOS-based millimeter-wave signal generator capable of modulating its frequencies across a wide band of 76-81 GHz at the world’s fastest speeds. This development, ...
