Cascading OPAMPs For Increased Bandwidth

Circuits and Calculation

The Bandwidth of an Operational Amplifier Circuit quickly drops when "some gain" is needed. To overcome this, opamps in series may help to increase the overall Bandwidth. This tools shows you the interrelation between number of amplifiers, GBWP, overall Bandwidth and overall Gain.

Cascading OPAMPs

A three stage design lowers the GBWP by a factor of ~ 11 compared to a single stage design.

Desired Bandwidth



Desired Gain



Number of OPAMPs



Necessary GBWP per OPAMP


Gain per stage


All stages assumed to be identical.
