<p>An oscillator having multi-phase complementary outputs comprises a first plurality of single ended bistable amplifiers (A1-A3) connected in series to form an input and an output and a second plurality of single ended bistable amplifiers (A4-A6) connected in series to form an input and an output. The first and second plurality have the same odd number of amplifiers. A first feedback path (FB1) connects the output to the input of the first plurality of amplifiers to establish bistable oscillations in the first plurality of amplifiers at a frequency dependent upon the delay time from the input to the output of the first plurality. A second feedback path (FB2) connects the output to the input of the second plurality of amplifiers to establish bistable oscillations in the second plurality of amplifiers at a frequency dependent upon the delay time from the input to the output of the second plurality. A first locking circuit (L1) is connected between comparable first points in the first and second plurality of amplifiers to ensure that the first points are oscillating in complementary fashion and a second locking circuit (L2) is connected between comparable second points in the first and second plurality of amplifiers to ensure that the second points are oscillating in complementary fashion.</p> |
