Abstract:
An input receiver circuit for a signal line may receive inputs from other signal lines to mitigate crosstalk noise present on the signal line. In some examples, the input receiver circuit may include a transistor with a programmable width. In some examples, the input receiver circuit may include a bias current generator with a programmable current. The width and/or current may be programmed based on an amount of crosstalk noise introduced by the other signal line. In some examples, the input receiver circuit may include a resistance and/or a capacitance. In some examples the resistor and/or capacitor may be programmable. The resistance and/or capacitance may be programmed based on a duration of the crosstalk noise on the signal line.
