    Abstract: Die Erfindung betrifft eine Verstärkerschaltung und ein Verfahren zur Korrektur des Tastverhältnisses eines differentiellen Taktsignals (CLt, CLc) zu einem gewünschten Wert von 50 % mittels eines ein MOS-Transistorpaar (Tl, T2) aufweisenden Differenzverstärkers (1). Dabei wird das zu korrigierende Taktsignal (CLt, CLc) an einen jeweiligen Gateanschluss des MOS-Transistorpaars (Tl, T2) angelegt, ein differentielles analoges Tastverhältniskorrektursignals (DCt, DCc) durch jeweilige Integration des von jedem MOS-Transistor (Tl, T2) des Differenzverstärkers (1) an seinem Source/Drainanschluss abgegebenen wahren und komplementären Taktsignals (ACLt, ACLc) erzeugt und das so erzeugte differentielle Tastverhältniskorrektursignals (DCt, DCc) jeweils an die elektrisch voneinander getrennten Substratanschlüsse (Sl, S2) des MOS- Transistorpaars (Tl, T2) angelegt, so dass jeweils die Substratspannungen und damit die Einsatzspannungen der MOS- Transistoren (Tl, T2) des Transistorpaars gegensinnig beeinflusst werden.

    Abstract: The invention relates to an amplifying circuit and to a method for correcting the pulse duty factor of a differential clock signal (CLt, CLc) to give a desired value of 50 % using a differential amplifier (1) having an MOS transistor pair (T1, T2). According to said method, the clock signal (CLt, CLc) to be corrected is applied to the respective gate of the MOS transistor pair (T1, T2), and a differential analog pulse duty correction signal (DCt, DCc) is produced by respective integration of the true and complementary clock signal (ACLt, ACLc) emitted by every MOS transistor (T1, T2) of the differential amplifier (1) on its source/drain connection. The differential pulse duty correction signal (DCt, DCc) thereby obtained is applied to the respective electrically insulated substrate connections (S1, S2) of the MOS transistor pair (T1, T2) so that the substrate voltages and the cutoff voltages of the MOS transistors (T1, T2) of the transistor pair are influenced in the opposite direction.
