  • Patent number: 4572974
    Abstract: A signal-level converter for controlling digital MOS circuits, particularly an address-buffer circuit for dynamic MOS memories, is designed in integrable form in MOS technology and is addressed on one hand by a first supply potential and a second supply potential connected as the reference potential, and on the other hand, at a signal input by the digital control signal to be processed, and furthermore includes cross-coupled field-effect transistor pairs as well as two output terminals carrying signals inverted relative to each other for controlling the digital circuit.

  • Patent number: 4565933
    Abstract: Integrated pulse former constructed in MIS circuit technology and connected to a first supply potential as well as to a second supply potential serving as a reference potential, and acted upon by control pulses from a pulse generator, which includes a first former part and a second former part directly addressed by the control pulses from the pulse generator, the first former part being connected to both the first and the second supply potentials and having three signal outputs, the second former part being additionally controlled via the three signal outputs of the first former part and being connected only to the first one of the two supply potentials, a first one of the signal outputs connected to and controlling a gate of a first field-effect transistor having a source-chain path directly connected, on one hand, to an output of the pulse generator furnishing the control pulses and, on the other hand, to a signal output of the second former part for furnishing secondary pulses, a second one of the three si
