    摘要: A signal delay circuit includes a driving circuit for driving an output signal with a voltage swing voltage between a supply voltage and a ground voltage. The signal delay circuit further includes a varactor load which is coupled to the output signal and has a capacitance which increases according to the supply voltage within a variation range of the supply voltage. The varactor load keeps the delay characteristic of the signal propagation circuit independent of the change of the supply voltage, thereby ensuring high speed operation and improved reliability of the CMOS semiconductor integrated circuit.

    摘要: Timing-signal delay equipment which provides an adjustable delay time, equal to a multiple of a predetermined time unit, to an input signal pulse is used as a timing source required in a circuit tester of LSIs (semiconductor large-scale integrated circuits). The timing-signal delay equipment has a plurality of delay elements (D.sub.ij 's) with weighted delay times arranged in a matrix form; a selector (S) coupled with the matrix for selecting one of the delay elements for each column of the matrix, wherein the selected delay elements are connected in series; and an arithmetic control circuit (M) that controls the selectors based on a set-up value of delay time and an error in delay time of each delay equipment. In order to provide a delay time which is equal to a multiple of a predetermined time unit in spite of an error in delay time of each delay element, either a correction matrix is connected in series to the matrix or the weight of each delay element is modified.

    摘要: A delay circuit is described having a variable capacitor and a triggering circuit. The variable capacitor and the triggering circuit may both comprise transistors. With both the variable capacitor and the triggering circuit dependent on the threshold voltage, the delay circuit may be less sensitive to process variations. The delay circuit may also include a capacitor, a first triggering circuit, a second triggering circuit, and a pull down circuit. The capacitor may discharge at a first rate, triggering the first triggering circuit which, in turn, activates the pull down circuit to pull down the capacitor at a second rate that is faster than the first rate. The second triggering circuit is triggered as the capacitor is pulled down, thereby reducing the effect of input signal noise on the output of the delay circuit. The discharging of the capacitor may be adjusted by a control input thereby making the delay of the delay circuit programmable.

    摘要: A method and apparatus for increasing the delays in transitions at controlled terminals in a non-linear integrated circuit by increasing the effective capacitance at the controlled terminals. This can be accomplished by capacitively cross-coupling at opposing phase controlled terminals. The capacitive crosscoupling is effected by connecting two P/N junction diodes in series with opposite directions of conductivity such that the capacitances across the junctions of the diodes are effectively connected in series.
