PPA IMPROVEMENT FOR VOLTAGE MODE DRIVER AND ON-DIE TERMINATION (ODT) - A simplified explanation of the abstract

This abstract first appeared for US patent application 17949990 titled 'PPA IMPROVEMENT FOR VOLTAGE MODE DRIVER AND ON-DIE TERMINATION (ODT)

Simplified Explanation

The patent application describes systems and methods for improving the power, performance, and area (PPA) for a voltage mode driver and on-die termination (ODT). The voltage mode driver includes first and second circuits in a pulldown design, with the first circuit having multiple nMOS devices in parallel and the second circuit having an nMOS device in series with a resistor. The second circuit is enabled when the pulldown impedance of the first circuit is greater than a desired value.

Original Abstract Submitted

Systems and methods for improving the power, performance, and area (PPA) for a voltage mode driver and on die termination (ODT). A voltage mode driver having first and second circuits in a pulldown design. The first circuit has a plurality of nMOS devices in parallel, the plurality of nMOS devices being common to a first resistor. The second circuit is in parallel with the first circuit and has an nMOS device in series with a second resistor. The second circuit is configured to be enabled when the pulldown impedance of the first circuit, with the second circuit disabled and all of the nMOS devices of the first circuit turned on, is greater than a desired pulldown impedance. The voltage mode driver may also be a pullup design, or have both pulldown and pullup stages.
