Transimpedance Amplifier Cutoff Frequency - Cypress.com Forums http://www.cypress.com/? Re: Transimpedance Amplifier Cutoff Frequency http://www.cypress.com/?rID=53553 From what I observe, the calculation of bandwidth of TIA is dependent not only on the feedback resistor and feedback capacitor, but also on the power setting selected.

 

The bandwidth is definitely inversely proportional to the product of resistor and capacitor. But if the power mode is set to "High Power", then the Bandwidth is higher. But if the power setting is set to "Minimum Power", then the Bandwidth is miniumum.
