ABSTRACT:
A receiver is described for recovering digital data from a transmitted balanced signal where the balanced signal includes a first plurality of pulses, each pulse having a first pulse width. The receiver includes an input circuit, a buffer circuit, and a calibration circuit. The input circuit receives the transmitted signal and includes a first differential amplifier for amplifying a first signal, a second differential amplifier for amplifying a second signal, and a converter for receiving the amplified first signal and amplified second signal and then generating a third signal. The first and second signals are included within the transmitted signal. The buffer circuit receives and buffers the third signal, and outputs a fourth signal including a second plurality of pulses which have a second plurality of pulse widths. The calibration circuit receives the fourth signal. In response to the second plurality of pulse widths being unequal to the first pulse width, the calibration circuit generates a calibration signal. The calibration signal is received by the buffer circuit as an input. The buffer circuit utilizes the calibration signal to modify the fourth signal so that each of the second plurality of pulse widths is approximately equal to the first pulse width.
