Delay circuit in PLL

How to implement the delay circuit in the PFD at the reset....is it two inverters connected in series ?

 

[wireless man]

this is one of the solutions. Alternatively, you can use the transmission gate.

Actually inverter provide very small delay,

Maybe you can use cap load to increase this delay.

I think normally the delay taken is in neno sec.

thanks
