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.

Abstract: A monolithic integrable R-2R resistor network comprises a number of series resistors connected to a terminal resistor; and a plurality of 2R resistor units each capable of being switched by two electronic switches either to ground or to another reference point, a different plurality of 2R resistor units being coupled to the nodes between each of the series resistors, to the node between the terminal resistor and the last resistor of the series resistors and to the node ahead of the first resistor of the series resistors. To compensate for the effects of the variations of the switch resistances caused during manufacture by process parameter fluctuations upon the accuracy of a D/A converter, a switch structure is inserted at each of the nodes which, with respect to the two electronic switches, is of the same kind, and which is permanently in an electrically conducting state. Preferably, there are used insulated-gate field-effect transistors and insulated-gate field-effect transistor structures, the identical electrodes of which, for example, the source electrodes, are directly connected to each of the nodes.
