Abstract

The invention relates to a circuit arrangement which can be integrated and consists of MOS transistors for counting 1 allocations in (0,1) vectors having n components. The counting circuit contains a network of basic cells (Gix) which are arranged in the form of a branching tree structure having rows and columns, the first row having one basic cell (G11), the second cell having two basic cells (G21, G22) and so on. Each basic cell consists of two transistors (Tix1, Tix2) which are controlled in antiphase and whose drain electrodes are connected to one another and form a switch input. The source electrodes of the transistors (Tix1, Tix2) form separate switch outputs. The switch outputs of the basic cells (Gn1 to Gn,n) of the last row are connected to the outputs (A1 to An+1) of the counting circuit. Depending on the 1-allocation which is present in each case, the drain voltage (VDD) which is applied to the switch input of the basic cell (G11) of the first row via a load transistor (TL) is switched through to one of the outputs (A1 to An+1) as a logic "1". All the other outputs are unambiguously connected to the source voltage (VSS) with the aid of further transistors (Ti13, Ti, i+1) which are controlled corresponding to the 1 allocation. <IMAGE>
