Abstract

An analog-digital hybrid IC device for reducing cross-talk adds an electrostatic capacitance element to the power supply side and/or the ground side of a CMOS logic circuit forming the digital circuit part, connects a resistance between the electrostatic capacitance element and the terminal to which the electrostatic capacitance element was added, and buffers charging and discharging when the logic elements switch on and off to reduce noise produced by current peaks.
