ABSTRACT:
A quadrant generator for generating a pair of pulse trains maintained in perfect phase quadrant with one another. The quadrature generator includes a feedback control loop for altering the duty cycle of an oscillating signal applied to a master-slave flip-flop pair configured to generate a pair of pulse trains maintained in a relative phase relationship. The feedback control loop controls the duty cycle of the oscillating signal applied to the master-slave flip-flop pair which, in turn, is determinative of the phase relationship between the pulse train pair generated by the master-slave flip-flop pair. When the pulse trains generated by the flip-flop pair are beyond phase quadrature, a control signal generated by the feedback control loop alters the duty cycle of the oscillating signal applied to the flip-flop pair to alter the phase relationship between the pulse trains of the pulse train pair.
