Abstract: System and method for providing precision a self calibrating resistance circuit is described that provides for matching a reference resistor using dynamically configurable resistance networks. The resistor network is coupled to the connection, wherein the resistor network provides a configurable resistance across the connection. In addition, the resistor network comprises a digital resistor network and an analog resistor network. Also, the circuit includes control circuitry for configuring the configurable resistance based on a reference resistance of the reference resistor. The configurable resistance is configured by coarsely tuning the resistor network through the digital resistor network and fine tuning the resistor network through the analog resistor network.

Abstract: An off-chip driver circuit can operate in an output mode to drive a signal supplied at its input terminals to an output terminal. It can also operate in an input mode in which signals are driven from an external circuit via the output terminal onto the chip. In an output mode, the output terminal is clamped to reduce the effect of overshoot voltages, for example as a result of reflections from the external circuits.

Abstract: An off-chip driver circuit having circuitry for providing protection against high voltages when the off-chip driver circuit is disabled is described. The circuitry for providing protection against high voltages utilizes a minimum number of transistors and therefore minimizes the chip area utilized by the off-chip driver circuit. An off-chip driver circuit has an input terminal and an output terminal. A pull-up transistor has a controllable path connected between a first power supply voltage and the output terminal of the off-chip driver circuit, and a control terminal connected to the input terminal via a pass gate connected to isolate the input terminal from high voltages applied to the output terminal. A control transistor has a controllable path connected between the control terminal of the pull-up transistor and the output terminal, and a control terminal connected to a control potential.
