Assignee: ARM LIMITED
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 19:
20. A device comprising:
an output stage having output transistors that receive tracking signals and provide an input-output pad voltage to an input-output pad based on the tracking signals;
a gate tracking stage that receives operational voltages, receives node voltages and provides the tracking signals to the output transistors based on the operational voltages and the node voltages;
a mode tracking stage that receives the operational voltages, receives the input-output pad voltage as a feedback voltage, and provides the node voltages to the gate tracking stage based on the operational voltages and the feedback voltage;
receiver input tracking circuitry that receives the node voltages, receives the feedback voltage and provides a receiver input signal; and
receiver circuitry that receives the receiver input signal and provides a receiver output signal based on the receiver input signal.
