Level control of the signal produced by a transceiver coupled to a power distribution line

摘要

The level of the signal output by a transceiver of digital information coupled to a power distribution line during a transmission phase is regulated by comparing the current level (Iref) of said output signal with a pre-established minimum threshold (IL) and a pre-established maximum threshold (IH); reducing the current level (Iref) when said maximum threshold (IH) is exceeded by reducing the gain; and passing to a voltage mode control of said output signal when the current level (Iref) of the output signal becomes lower than said minimum threshold (IL). The architecture of a coupling interface implementing the above method is illustrated.
