ABSTRACT:
Calibration circuitry and method for maintaining constant signal detection thresholds for multiple signal receivers that receive data signals in the form of current signals. A value of one of the incoming current signals having a predetermined signal pattern is detected and used to generate threshold control signals for each of the signal receivers to control the data signal detection thresholds.
