A <inline-formula> <tex-math notation="LaTeX">$2{\boldsymbol \times }$ </tex-math></inline-formula>VDD I/O buffer based on deterministic PVT variation detection algorithms to achieve slew rate compensation is proposed in this brief. By using the P-PVT and N-PVT Variation Detectors consisting of an inverter and a capacitor, the slew rate variation is significantly reduced against the PVT variation. Besides, the source-drain leakage current is reduced by turning off the auxiliary current paths… CONTINUE READING
