MITIGATION OF POWER SUPPLY DISTURBANCE FOR WIRED-LINE TRANSMITTERS

A wired-line transmitter may include architecture that provides control of the current profile during power-up and/or power-down of the transmitter. The current profile may include a sloped ramp up during power-up and/or a sloped ramp down during power-down. The sloped ramps of the current profile m...

Zusammenfassung:A wired-line transmitter may include architecture that provides control of the current profile during power-up and/or power-down of the transmitter. The current profile may include a sloped ramp up during power-up and/or a sloped ramp down during power-down. The sloped ramps of the current profile mitigate supply bouncing during power-up and/or power-down. Individual enable signals may be derived from an enable signal provided to the transmitter. These individual enable signals may be provided (or turned off) in a time delayed (e.g., staggered) manner to provide the sloped ramps for the current profile.
