摘要: A quadrature generator (975, 1075) for generating a pair of pulse trains maintained in perfect phase with one another. The includes feedback control loop altering the duty cycle an oscillating signal applied to master-slave flip-flop (450, 650) configured generate relative relationship. controls (54, 58) which, turn, is determinative relationship between train generated by 58). When (450) are beyond quadrature, alters alter pair.
