Abstract :
A recirculating racetrack CCD, 150 bits in circumference has been fabricated utilizing new high speed methods for inputting and outputting charge through the side of CCD´s. These techniques use combined, simultaneous serial and parallel charge transfer; and have no detrimental effect upon the CCD transfer efficiency. Since charge may be clocked around the racetrack many times, this CCD facilitates highly accurate transfer efficiency measurements. Typical transfer efficiency measured at 1 MHz after 4800 transfers is 0.99986. No performance degradation due to the input or output structures is observed.
