Hey, guys! I would like some help inwith my SPWM circuit above. I need to insert a deadtime between the output from Comp_PWM and dont know how to do it very well.

I've used logic gate, but I don't think its effective.

Any help is welcome

JorgeSilva,

I seems like you are trying to produce a sine-modulated PWM output for DC-AC inverter. For that PSoC can provide a pure digital solution, which you can find in #3 of this thread:

Voltage Multiplication

Moreover, the PWM module provides free ph1 and ph2 outputs with deadtime insertion!

Should you insist on the traditional analog approach of designing own PWM, the deadtime insertion examples (both analog and digital) can be found in here:
