Abstract
A method and integrated circuit for the transmission of differential signals with a signal and a complementary signal is disclosed. For trimming the edge steepness of the signal with that of the complementary signal, the integrated circuit has a first driver for generating the signal, and a second driver for generating the complementary signal. A circuit is provided, configured to control the edge steepness of the signal or of the complementary signal.
Claims26
An integrated circuit comprising:
- a first driver configured to generate a signal;
- a second driver configured to generate a complementary signal;
- and
- a circuit configured to control an edge steepness of the signal or the complementary signal as a function of an output signal obtained from the signal and the complementary signal.
