    摘要: The circuit configuration for the generation of clock signals for a semiconductor memory (14) that are edge-synchronous with the output signals of a clock generator (16) comprises an input stage (20) to which the output signals of the clock generator (16) are applied. It furthermore contains a phase detector (30) which receives the signals output by the input stage (20) and whose output signals control a voltage-controlled oscillator (34) which supplies the clock signals for the semiconductor memory (14). It also contains a conversion stage (42) which applies signals related to the output signals of the oscillator (34) to the phase detector (30), which controls the oscillator in such a way that the phase difference between the signals reaching it from the input stage (20) and the signals also reaching it from the conversion stage (42) becomes zero. The input stage (20) comprises an amplifier (44) containing a circuit component (62) capable of influencing the signal transit time. This circuit component (62) is controlled in such a way as to change the signal transit time in inverse proportion to the changes of the output signals of the clock generator (16).

    摘要: A driver circuit generates an adjustable output signal current at a driver output, which corresponds in each case to one or the other binary data level of an input signal. The driver circuit comprises n partial driver circuits (TT1-TT7), connected in parallel both at the input and at the output sides, which may be set into either an active or an inactive state for the purpose of setting the output signal current by means of a setting signal. In their active state each driver circuit delivers at each of its outputs a partial signal current relative to a constant reference current (Iref), depending on the data level of the input signal. The sum of the partial signal currents corresponds to the set output signal current. The input signals (INP, INN) are applied to a first partial driver circuit (TT1) directly, and to a second to nth partial driver circuit (TT2-TT7) via 1, 2, ... or n-1 delay elements (DP1-DP6, DN1-DN6) after a time delay of 1xΔt, 2xΔt up to (n-1)xΔt.
