ABSTRACT:
A digitizer for a digital receiver system includes an input terminal to receive a modulated analog input voltage signal, and an output terminal to provide an output voltage signal being a digital conversion of the input voltage signal. A comparator circuit has an output coupled to the output terminal and includes an operational amplifier having a first input terminal coupled to the input terminal. A threshold generator circuit is between the input terminal and a second input terminal of the at least one operational amplifier, to provide a tunable voltage reference signal thereto. The threshold generator circuit includes a thresholding circuit to determine a threshold voltage value of the modulated analog input voltage signal, and a tunable voltage reference circuit coupled to the thresholding circuit to generate the tunable voltage reference signal as a function of the threshold voltage value of the modulated analog input voltage signal.
