摘要： To avoid interference signals caused by overlapping edges of a switching signal for driving p-channel-transistor/n-channel-transistor pairs, a drive circuit contains a first series combination of the current paths of a first p-channel transistor, a first n-switching transistor, and a first n-channel transistor and a second series combination of a second p-channel transistor, a second n-switching transistor and a second n-channel transistor, with the gate of the first p-channel transistor connected to the current-path junction of the second series combination, and the gate of the second p-channel transistor connected to the current-path junction of the first series combination. The switching signal and the inverse thereof are applied to the gates of the first n-channel transistor and the second n-channel transistor, respectively. The gates of the n-switching transistors are presented with the n-clock. The first and second current-path junctions are followed by a first inverter and a second inverter, respectively. If the transistor pair is to be turned on by the L or H level of the switching signal, the gate of the n-channel transistor of the pair is connected to the first current-path junction or the second current-path junction, respectively, and the gate of the p-channel transistor to the output of the first inverter or the second inverter, respectively.

摘要： A circuit checks for coincidence of a data word with a reference data word by means of EXOR gates per digit of the two data words, and a non-coincidence is permitted in a number of digits (m). The output signal that appears at the output of the circuit is the result of the current flowing therein, with the sign thereof being indicative of either a coincidence or a non-coincidence. For this purpose, the individual outputs of the EXOR gates serve to activate switch transistors with the aid of which standard currents (i) are caused to flow from the output, via an N-multiple current source, to the zero point of the circuit (ground). On the other hand, via a first P-current mirror, a current mi and, via a second P-current mirror, a current i/2 are fed to the output. By means of the N-multiple current source, the current mi is impressed upon the current input of the first P-current mirror.
