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 ...

Figure 1 Analog PWM circuit using triangle wave generator and comparator In this Design Idea, we show an alternative circuit. It uses very little power, can be implemented in a small silicon area, and ...

Timing is everything and generating clocks based off a PWM signal is often useful. The same circuit generates up to eight independent clocks using a shift-register.

Download Design Note 538 (PDF) Introduction Pulse width modulation (PWM) is a common technique for generating analog voltages from a digital device such ...

A circuit diagram of a driving motor using a variable DC source. When using a PWM source, the circuit sees Ohmic resistance and inductance due to frequent switching.

Even if it might not be as widely used as [Jana’s] earlier work that combines an oscilloscope and signal generator, having a tool that you can rely upon to test servos and generate a PWM can be ...

Ideally, I suppose a solution would be to generate a ramp that was synchronized with the pwm signal, and use a sample and hold circuit to grab the ramp’s voltage when the pwm’s edge appeared. In your ...

It is difficult to get noise free signal in microwave frequency range of 30 gigahertz and above, Fujitsu has announced millimeter wave low noise signal generator circuit for automotive radar and other ...

To characterize the signal processing properties of a circuit, one must measure how it transforms a wide range of dynamical inputs into outputs. Recently, gene circuits have been dynamically ...
