Novel CMOS/BiCMOS Drivers Applied to On-chip Interconnects

For improving s ig nal levels and driving ability and so on between double chip interconnects, a n umber of CMOS/BiCMOS drivers for on chip interconnections are designed, and som e main ideas of fabricating the designed CMOS/BiCMOS drivers by means of advance d 0.5 μm process and technology are also proposed in this paper. PSpice simula tion and experiment result demonstrate that the proposed CMOS/BiCMOS drivers wil l be operated down to sub 3.3 V , which not only confirms the low powe r dissipation and low supply of CMOS part, but also gains the advantages of high speed and large driving ability of bipolar part, so that these CMOS/BiCMOS driv ers are very suitable for high speed, low power dissipation and low supply digit al information system.
