Abstract
A pad calibration circuit with on-chip resistor. An integrated circuit with an impedance terminated output terminal is disclosed. A source is provided for sourcing current to the output terminal of the integrated circuit, which output terminal interfaces with a load having a finite impedance associated therewith. An on-chip source impedance is disposed internal to the integrated circuit and between the source and the output terminal to define the input impedance of the output terminal.
