Superiority of Current mode over Voltage mode Interconnects
نویسندگان
چکیده
In deep submicron VLSI circuits, interconnect delays dominate MOSFET gate delays. Conventional buffer insertion method reduces delays at the cost of valuable chip area. Consequently, alternative methods are essential. Current mode interconnects have lesser delay than voltage mode circuits and also consume lesser chip area. In the present work, superiority of current mode over voltage mode interconnects is analyzed. The simulative analysis is carried out using Tanner EDA tools.

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...
