ABSTRACT:
Arrangement allowing an input bucket brigade (BBD) stage to feed several other BBD stages in parallel with no loss of the signal transferred from the input stage to the subsequent ones. An input voltage corresponding to a charge quantity is stored in the second capacitor of the input BBD stage. The drain of the output transistor of the input stage is connected to a first BBD stage wherein the first capacitor is connected to the source electrode of the first transistor of a second BBD stage. The first transistors of both stages are controlled by the same clock pulses. When these transistors are turned on, the capacitors connected thereto are in series with the second capacitor of the input stage. Consequently, the same current will flow through these capacitors, which will thus store the same charges so that the charge representing the input voltage will be reproduced in the first capacitors of the two BBD stages connected to the input stage. Means are provided for grounding the terminal of the first capacitor in the first stage that is connected to the source of the first transistor in the second stage at the time the transfer of the duplicated charge takes place.
