Abstract

PURPOSE:To greatly simplify the unit construction, by injecting a part of each transfer charge every bit of the first and second CTDs to each bit of the third CTD and sequentially transferring and outputting the charge in the frequency which is 1/2 times the specified frequency. CONSTITUTION:The first CTD1 sequentially transfers the charge corresponding to the information signal S1 injected via the input terminal 23 in the repetitive frequency f1 with a given ratio determined, for example, with D11...D15 for each bit. Next, the second CTD2 is connected to the terminal 23 via the phase inversion circuit and sequentially transfers the charge corresponding to the phase inversion signal S1' of the signal S1 with a given ratio determined, for example, with each bit D21...D25, in frequency f1. Further, the third CTD3 is coupled with DTDs1 and 2 so that a part of each transfer charge every bit of CTDs1 and 2 can injected to the bits D31...D35, and the charge injected is sequentially transferred to the output terminal 24 in the frequency f2 of 1/2 times the frequency f1. Thus, the unit construction can remarkably be simplified.
