Abstract:
1. A semiconductor device comprising: a signal-transmission interconnection for transmitting signals; a MOS capacitance element having a source, a drain, a well, and a gate electrode connected to said signal-transmission interconnection; a first voltage-applying interconnection being connected to said source and said drain of said MOS capacitance element, and said first voltage-applying interconnection being configured to apply a voltage to said source and said drain of said MOS capacitance element; and a second voltage-applying interconnection being connected to said well of said MOS capacitance element, and said second voltage-applying interconnection being configured to apply a voltage to said well of said MOS capacitance element, wherein the voltages of said first and second voltage-applying interconnections are controlled independently from each other.
