- Abstract
- For multi-Gb/s/pin parallel dynamic random access memory (DRAM) interface, a crosstalk cancelling voltage-mode driver is proposed. The voltage-mode driver is composed of a main driver and sub-drivers where the cancellation signal is generated by the sub-drivers. The outputs of the main driver and sub-drivers are combined by a capacitive coupling so the direct current (DC) output swing is not affected by the crosstalk cancellation and the sub-drivers may not consume DC power. The proposed crosstalk cancelling voltage-mode driver implemented in a 0.11-mu m complementary metal-oxide semiconductor (CMOS) technology improves the horizontal eye openings by 22.6ps at 4-Gbps/pin.
