Abstract: The binary values of the data word to be converted in a widely used type of D/A converter are supplied to a series of stages in which binarily stepped currents are supplied to a common output or derived therefrom, or are conducted to a second common output. To control the current switch, each stage comprises a flipflop in which the binary value to be converted is stored. Integration processes are often used in the integration of analog circuits by means of which digital circuit components cannot be usefully realized, for example, in the IIL technology. In the flipflop comprising cross-coupled transistors, the emitters are connected to a reference voltage which lies between ground potential and the supply voltage so as to obtain a favorable conversion of the digital signals for triggering the current switch. This renders it possible to connect the collectors of the transistors of the flipflop directly to the bases of the current switch.

Abstract: A current supply arrangement, for supplying at least one load with electric energy from a source, includes a switching stage for optionally switching-on the load according to a switching signal applied thereto and a control circuit which, in its switched-off state, cuts the supply of energy to the switching stage and, to the load and in its switched-on state, controls the energy supply to at least the switching stage. Current supply arrangements of such a type are used more specifically in television sets having remote control for "normal operation" and a "stand-by mode". So as to obtain for this arrangement the advantages of the "stand-by mode" and, on the other hand, to reduce the electrical power consumed and also the number of modules loaded by heating or voltage charges, the switching signal is also applied to the control circuit for switching between the switched-off and the switched-on states.
