  • Method and circuit for compensating for the offset voltage of electronic circuits
    Patent number: 10833689
    Abstract: The present invention corresponds to a method and a circuit for compensating the offset voltage of electronic circuits, where the circuit implementing the method comprises: a dynamic comparator (1); a phase detector (6) connected to the dynamic comparator (1), the phase detector (6); a finite-state machine (9) connected to the phase detector (4), a first digital-analog converter (12) connected to an output of the finite-state machine (9); a second digital-analog converter (13) connected to another output (11) of the finite-state machine (9); a polarization block (14) with a first input (15) connected to the output of the first digital-analog converter (12) and a second input (16) connected to the output of the second digital-analog converter (13); where the polarization block (14) polarizes an electronic circuit (17) and the dynamic comparator (1), the phase detector (6), and the finite-state machine (9) are connected to a clock signal (3).
