Laser powered clock circuit with a substantially reduced clock skew |
摘要 |
A synchronous clock signal is generated in a large number of local clock circuits at the same time by exposing photoconductive regions in each local clock circuit to a pulsed light source that operates at a fixed frequency. The photoconductive regions generate photoconductive currents which are sufficient to cause a logic inverter to switch states.
