| Abstract(in English) | Simultaneous switching current generated by operation of a CMOS circuit is injected into the CMOS substrate, and causes the substrate voltage bounce. The performance of the circuit degrades due to the voltage bounce. In this report, we focus on the fact that parasitic couplings in the CMOS substrate and parasitic inductance in the power and ground connection form a bridge circuit, and we demonstrate that the voltage bounce can be suppressed by controlling variable resistances that are inserted between the substrate resistive coupling and the conductor line for the power supply. The effectiveness of this method is verified with a quad flat package (QFP) and we reduced the voltage bounce about 40 dB. |
