Protocol compliant high-speed DDR transmitter

Abstract:

Implementations described herein relate to circuits and techniques increasing transmitter output speed. In some implementations, a circuit is described using a pull-up data path comprising a first flying capacitor, a first buffer, a thin-oxide PMOS device, and a thick-oxide PMOS device, a pull-down data path comprising a second flying capacitor, a second buffer, a thin-oxide NMOS device, and a thick-oxide NMOS device, wherein the pull-up data path and the pull-down data path are operatively connected to a core data output signal line.
