Abstract: A controller for an electronic circuit that includes a first and a second switch is provided. The controller includes an event detector stage that receives logic electrical signals and a pulse generator circuit, which is coupled to the event detector stage and generates a dead time signal based on edges of the logic electrical signals detected by the event detector stage. The dead time signal includes pulses delimited by an edge of a first type and by a subsequent edge of a second type. A combinatorial sampling circuit generates a first and a second sampled preliminary signal. An update stage updates the values of the first and the second control signals at each pulse of the dead time signal based on the first and the second sampled preliminary signals, subsequently to the edge of the first type or the second type of the pulse of the dead time signal.
