Abstract:
An electrical circuit for conversion from differential to single-ended includes a differential amplifier stage and first and second buffer circuits. The differential amplifier stage includes a first and a second input; and a first and a different second charging circuit that can be operatively coupled, respectively, with an output of the conversion circuit and with an auxiliary output. Each of the first and second buffer circuits is functionally arranged between one of said outputs and between one of said charging circuits. The buffer circuits being configured so as to substantially equalize relative impedances seen towards said outputs.
