Hi Friends,

Can any person tell me how to compute the Group delay of a Filter using CADENCE tool?

Best regards.

pspice group delay

with the phase shift and frequency information of the filter, you can use the calculator of CADENCE to get the delay

Most of the simulator programs have a capability to directly display the group delay - for example, by displaying in PROBE the results of an ac analysis from PSPICE you can command G(V(out)). This gives you the group delay as a function of frequency for the signal at node "OUT".
