High-speed and low-swing on-chip bus interface using threshold voltage swing driver and dual sense amplifier receiver

A new high-speed and low-swing on-chip bus interface using Threshold Voltage swing (Vt) driver and Dual Sense Amplifier (DSA) receiver is proposed. The Vt-driver reduces the rising time in the bus to 30% of the full CMOS inverter and the DSA-receiver increases twice the throughput of the conventional reduced-swing buses using sense amplifiers. With Vt-driver and DSA-receiver combined, approximately 60% speed improvement and 75% power reduction are achieved in the proposed scheme compared to the conventional full CMOS inverter for the on-chip bus interface.
