  • Patent number: 7391279
    Abstract: A bypass capacitance is connected to a node between first and second self-bias resistances connected in series between an input and an output of an inverter. The bypass capacitance accommodates changes in the output voltage of the inverter to suppress the feedback effect from the output side to the input side of the inverter. That is, the bypass capacitance plays the role of suppressing a decrease in the input impedance by the Miller effect.
