Abstract:
1. A clock supplying apparatus for supplying a clock to a digital circuit, comprising: a plurality of clock supplying units; each of said clock supplying units including: a differential clock driver configured to receive an original clock inputted thereto and generate a first a clock of a positive phase and a second clock of a reverse phase from the original clock; a first clock line along which a first clock of a positive phase from said clock driver propagates; a second clock line along which a second clock of a reverse phase from said clock driver propagates; a parallel resonance circuit of an inductor and a capacitor; a first passive element connected to said first clock line; and a second passive element connected to said second clock line; said inductor of said parallel resonance circuit being connected at a first end to said first clock line and at a second end to said second clock line; said capacitor of said parallel resonance circuit being connected at a first terminal thereof to said first clock line and at a second terminal to said second clock line; the first passive elements of said clock supplying units being connected to each other while the second passive elements of said clock supplying units are connected to each other.
