PHN 11 430 13 26-3-1986 ABSTRACT: Integrated circuit. Charge-coupled devices are very sensitive to clock cross-talk due to the overlap between successive electrodes. The influence of this cross-talk is reduced when the clock lines are periodically connected to earth via a low-ohmic impedance. For this purpose, each clock line is controlled from a buffer (15, Fig. 4), whose output (O) is connected to a clock line. A clamping transistor (T20) is connected between the output (O) and the earthing point (Vss). When this clamping transistor is controlled by means of the output signal (O) (via the inverter T21, T22) and at the same time by the input signal of the buffer (15) (via the series - combination of the inverters T23, T24 and T25, T22), the output (O) is clamped at Vss at the instant at which the cross-talk is expected by means of only a single clamping transistor. Fig. 4.
