The conditions necessary for synchronizing the velocity of the wave with the drift velocity of charge carriers in the CCD channel are derived. Meander-line clocking for operation of silicon CCDs in this traveling-wave mode appears to be feasible with present technology for clock frequencies in the range of 1 to 250 GHz. At synchronism, diffusion-limited inefficiency in charge transfer is eliminated, allowing operation at high frequencies where surface-state-limited inefficiency is negligible so that transfer efficiencies approaching 100% should be achievable.
