Abstract
A current pulse generator with process-independent and temperature-independent symmetric switching times, includes a differential stage which is adapted to generate a transmission current and a circuit for driving the differential stage which is adapted to generate a control voltage for the differential stage. The generator also includes a circuit for compensating the variations in the values of degeneration resistors of the differential stage, to generate, with the differential stage driving circuit, a current for controlling the differential stage, to keep the switching times of the current pulses of the generator substantially unchanged and symmetrical despite variations in the manufacturing process of the generator and the temperature.
