Hello,
I'am using afe4490 for a reflective PPG wrist application and iam trying to find the best configuration for the TIA amplifier.
I choosed SFH 2430 photodiode which has a capacitance of 1000pF. Do you have any method to calculate Rf and Cf of TIA to achieve a stable frequence response?
Best Regards,
Vítor Pinto
