Summary: 
This letter proposes an output driver which reduces simultaneous switching noise without degradation of rise/fall time. At the start of transition period, the driver optimally uses both VDD and VSS current by switching of on-chip bypass capacitors. The proposed driver achieves 27-percent reduction in peak current with faster transition time.
