Abstract:
A current bit cell comprising a current source (P1), means (P6) for detecting the presence of a digital signal bit (Bit) and means (P2, P5, P7) for detecting at least one command signal (L, Lc) so as to command, on a first output (S1) of the cell, the appearance of a current delivered by the current source (Pi) as a function of the digital signal (Bit) applied to the said cell and of the said at least one command signal (L, Lc), means (P9) for detecting the presence of a bit (Bitz) complementary to the bit of the digital signal (Bit) and means (P3, P4, P8) for detecting the complement (Lz, Lcz) of the said at least one command signal (L, Lc), so as to command on a second output (S2) of the cell the appearance of a current delivered by the current source (P1) which is the complement of the current delivered on the first output (S1), the said means for detecting the presence of bits and of the said at least one command signal, the said means for detecting the presence of complementary bits and of complementary command signals and the said current source being embodied with the aid of field-effect transistors of the same type.
