Abstract
Disclosed is a time delay generatorapparatus and method. The apparatus includes a time delay gate, a mixer(a Gilbert cell circuit), and a current digital to analog converter. The mixer, comprised of first and second transistor differential pairsand, receives an analog input signalwithout a delay as well as a delayed input signalproduced by the time gate delay. The digital to analog converter regulates the relative current flow between a first control signaland a second control signal, effectively altering the mixing of the undelayed input signaland the delayed input signalto generate a delayed output signalwith a time or phase delay substantially equal to the temporal delay represented by the digital signal input. The time delay generator exhibits reduced phase noise and a linear time delay response.
