  • MOSFET Integrated delay circuit for digital signals and its use in color-televison receivers
    Patent number: 4489342
    Abstract: To adjust time delays in equidistant steps, an inverter chain is provided with an even number of static inverters of identical topology. The output of one of the even-numbered inverters is connected to the signal output via a selector switch. During suitable frequency-measuring periods, an odd number of inverters is connected to form a ring by directly coupling the output of an odd-numbered inverter to the input of the first, and a digital measuring arrangement determines the time delay of the ring-connected portion from the frequency of the ring's self-excited oscillation. The output signal of the measuring arrangement is used to adjust the time delay of the inverter chain.

  • Monolithic integrated circuit for a digital-to-analog converter
    Patent number: 4331892
    Abstract: A monolithic integrated digital-to-analog converter is provided wherein the resistors are replaced by insulated-gate field-effect transistors thus avoiding any detrimental effects of variation between supposedly identical components. The equivalent resistance values of the insulated-gate field-effect transistors are determined by a fixed ratio of channel width to channel length.
