An electronic circuit comprises an input stage and a driver stage. The input stage comprises first, second, third and fourth inputs, and is configured to generate a first intermediate signal which is the sum or the weighted sum of the first and third input signals, and a second intermediate signal which is the sum or the weighted sum of the second and fourth input signals. The driver stage comprises an output, is configured to generate an output signal present at the output, and is configured to directly compare the first and second intermediate signals such that the output signal indicates which of the two intermediate signals is larger.
