Abstract
One example includes a communication system. The system includes a data transmitter configured to generate a digital communication signal and a data receiver configured to receive the digital communication signal. The system also includes a pulse-width distortion (PWD) correction circuit arranged between the data transmitter and the data receiver and being configured to adjust at least one timing parameter associated with the communication signal.
Claims20
A communication system comprising:
- a data transmitter configured to generate a digital communication signal;
- a data receiver configured to receive the digital communication signal;
- and
- a pulse-width distortion (PWD) correction circuit arranged between the data transmitter and the data receiver and being configured to adjust at least one timing parameter associated with the digital communication signal.
A method for correcting pulse-width distortion in an isolated communication system, the method comprising:
- receiving a digital communication signal from an isolation barrier;
- filtering the digital communication signal to generate an average voltage corresponding to an average voltage amplitude of the digital communication signal;
- comparing the average voltage with a predetermined reference voltage;
- and
- delaying at least one of a rising-edge and a falling-edge of the digital communication signal based on the comparison.
An isolator circuit interconnecting a data transmitter and a data receiver, the isolator circuit comprising:
- an isolation barrier configured to provide isolation of a DC-balanced digital communication signal that is transmitted from the data transmitter to the data receiver;
- and
- a pulse-width distortion (PWD) correction circuit arranged between the barrier and the data receiver and being configured to adjust at least one timing parameter associated with the DC-balanced digital communication signal.
