delay time control between two square wave

[applecat2411]

As i am trying to have two logic square waves signals with ampltiude of 5V to drive two MOSFETs in half- bridge configuration of my DC-DC converter. The frequency i am using is 100kHz, which is 10us for the period.


I need to control one of the signals having a delay time ranging from 0 to 5us with respect to another signal , are there any method to do this?


Thank you.

A network consisting of a series R and shunt C to the input of a logic inverter, preferably one with some hysteresis, such as the ones described here.

I am new to this thing, so would it be difficult to adjust the delay time? Because i think if i need to have different delay time, different capacitance should be used.

Have you looked at any of the many PWM control ICs that are designed for that purpose?

Use a trimpot to adjust the resistance. Use a 10KΩ pot and 1nF capacitor. With the pot set to midrange, you will get ~5us delay
