Abstract
Systems and methods are described for compensating for variations in process, voltage, temperature, or combinations thereof in an apparatus. An example apparatus may be a memory circuit. A pre-driver circuit and driver circuit may be associated with the memory circuit. A reference generator may provide the pre-driver circuit with reference signals that are insensitive to process, voltage, and temperature. The pre-driver circuit may receive the reference signals and the pre-driver circuit output ramping rate may then be made less sensitive to variations in process, voltage, and temperature. The pre-driver circuit output may then be supplied to a driver circuit that may then output a final driver data output with reduced noise.
