The problem that I have is that the offset of the output shifts.
It seems that the offset shifts progressively over time.
Here the description of the measurement setup:
I’m using a SAKURA-G board with the differential probe at VCC shunt on the 1.2 V rail.
The differential probe is connected to an oscilloscope.
The differential probe is powered by + - 5 V.
Before starting the measurement the target implementation is executed and the offset is adjusted to put it around zero, ensuring that the two feedback leds are off.
The power consumption signal is 16 mV (Vpp).
What do you recommend to have a fixed offset ?
