Multi-node Driving Circuits for Multi-branch Transmission Wires

摘要

In this paper, we propose multi-node driving circuits for multi-branch transmission wires. Power dissipation could be decreased remarkably by dividing the full signal swing into several low swings through charge redistribution. HSPICE simulations show that while driving three branches with load capacitance of 1pF each, the proposed scheme can save the power by more than 66% compared with the circuit from reference, under a voltage supply of 1.2V in 0.13um technology.
