The PLD (programmable-logic-device) code in Listing 1 creates arbitrary-resolution, pulse-width-modulated (PWM) generators. PWM generators are useful as low-bandwidth D/A converters in hardware of ...

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 ...

We love little tricks like this. Suppose that you want to generate an IR remote’s signal. It’s easy, because most of the codes are known. But it can be slightly harder because most IR remotes and ...

Linear Technology has unveiled a new pulse width modulation (pwm) generator with 48 independent channels. According to the IC specialist, each channel has an individually adjustable 12bit (4,096 steps ...

The LT3761 is a 60 V dc/dc controller designed by Linear Technology to operate as a constant-current source and constant-voltage regulator. The LT3761 is a 60 V dc/dc controller designed by Linear ...

Linear Technology Corp. introduces the LT3761, a dc/dc controller designed to operate as a constant-current source and constant-voltage regulator. Linear Technology Corp. introduces the LT3761, a ...

Last time, I showed you a simple PWM block and an open source UART core. This time, I’ll put these parts together to create a PC PWM output peripheral. With working code (working, at least, in ...

I have had an on-going mission to design a universal-ish pcb that will convert a PWM waveform at one frequency into to another frequency while retaining the mark-space ratio. The obvious answer is a ...
