Patent ID: 7304591

Claim:
A method for providing a digital output signal representing at least one analog input signal, comprising: (a) feeding an analog circuit with said at least one analog input signal and a plurality of discrete correction signals; (b) said analog circuit providing analog monitoring outputs, wherein said at least one analog input signal and said discrete correction signals are jointly related by a relationship to said analog monitoring outputs, said relationship having an identification algorithm; (c) receiving said analog monitoring outputs and a synchronization clock and implementing a negative feedback control loop by said feeding said analog circuit with said discrete correction signals, in order to keep at least one of said analog monitoring outputs to be within a previously defined constraint; (d) identifying said relationship thereby creating an internal representation of said relationship; (e) calculating said digital output signal by using a digital representation of said discrete correction signals and said internal representation, wherein said digital output signal represents said at least one analog input signal.
