Because I have an amplification stage, with a gain of 1250. That 60 mV drop is coupled to the amplifiers (60 mV x 1250). Altering my amplified analog signal.

When powering the ESP32 via the Vin pin and activating Bluetooth, I have noticed a voltage drop of approximately 60 mV occurring approximately every 600 milliseconds, as evidenced in the image provided. I'm looking for recommendations to eliminate this voltage fluctuation. What suggestions can you g...
