Abstract
A delay circuit with adjustable delay employs a switching flip-flop which includes a differential amplifier (A) having two outputs each one feedback-looped respectively onto two inputs, so as to produce the said switching. The looping is produced by a first (AD1) and a second (AD2) adder, each having a first, a second and a third input. The first inputs are connected to corresponding outputs of the differential amplifier to produce the feedback looping. The second inputs are intended to be connected respectively to a first and a second terminal delivering a signal to be delayed (V.sub.1.sup.+, V.sub.1.sup.-) and the third inputs receive respectively a first and a second control voltage (V.sub.3.sup.+, V.sub.3.sup.-). The delay is a function of the difference between the first and the second control voltage. The outputs of the adders are connected respectively to corresponding inputs of the differential amplifier.
