I need PWM pulses of 3.3V, and my micro-controller is giving 1.8V PWM signals. I have a voltage source of 3.3V. One way I am thinking is to use two cascaded inverters(like NOT-GATE) using MOSFETs. Is there any other good ways to do this?

Logic level converter: -
This one works with two Vcc levels from 0.8V to 3.6V.
