Patent ID: 8258882

Claim:
A clock signal distributing device comprising: a plurality of LC resonant oscillators, each resonating at a frequency corresponding to values of a first inductor and a first capacitor to oscillate a signal; an injection locked LC resonant oscillator that resonates at a frequency corresponding to values of a second inductor and a second capacitor to oscillate a signal that is synchronous with an input clock signal; and transmission lines that connect oscillation nodes of the plurality of LC resonant oscillators and of the injection locked LC resonant oscillator, wherein the injection locked LC resonant oscillator includes: a first p-channel field effect transistor having a gate connected to a first node, a source connected to a supply potential node and a drain connected to a second node; a second p-channel field effect transistor having a gate connected to the second node, a source connected to the supply potential node and a drain connected to the first node; a first n-channel field effect transistor having a gate connected to the first node and a drain connected to the second node; a second n-channel field effect transistor having a gate connected to the second node and a drain connected to the first node; a third n-channel field effect transistor having a gate connected to a node of the input clock signal and a drain connected to the source of the first n-channel field effect transistor; a fourth n-channel field effect transistor having a gate connected to a node of an inverted signal of the input clock signal and a drain connected to the source of the second n-channel field effect transistor; and a fifth n-channel field effect transistor having a source connected to a reference potential node and a drain connected to the sources of the third and fourth n-channel field effect transistors, wherein the second inductor is connected between the first and second nodes, and the second capacitor is connected between the first and second nodes.
