Hi everyone,
working through my project that consists in developing an integrated analog circuit for the readout of a sensor I'm now facing a new problem: how to fix the common mode input voltage of a fully differential amplifier that must work as a current integrator.
To be more precise: the fully differential is set with the two feedback capacitors for the integration, and there is a current signal source (that is the drain pin of the output mos of the sensor, whose voltage is not defined).
If anyone did understand or at least have an idea about the problem please let me know.Thanks
(The description is probably not so clear so for any doubt don't hesitate to ask)
