  • Clocking signal drive circuit for bucket brigade device
    Patent number: 4383326
    Abstract: A bucket brigaded device is provided which includes first and second clocking signal generators for generating a first set and a second set of clocking signals respectively, a plurality of successive capacitors for sequentially holding charge level representing an input signal, and a plurality of transistors for controlling the transfer of charge levels from one capacitor to another. Each of the transistors is connected between adjacent capacitors.The bucket brigaded device further comprises a first clocking signal driver for supplying one of the first set of clocking signals to each capacitor, and a second clocking signal driver for supplying one of the second set of clocking signals to each transistor.
