A 1+n/k Frequency Divider Unrelated to Duty Ratio of Multi-Phase Clock
Mitsutoshi Yahara, Kuniaki Fujimoto · IEEJ Transactions on Electronics Information and Systems · 2019
In this paper, we propose the 1+n/k frequency divider which does not depend on the duty ratio of the multi-phase clock. The proposed circuit does not have to waveform shape the multi-phase clock which is an input signal. Also, the frequency division range is not limited to n ≤ ⌊k/2⌋ (⌊x⌋ is the largest integer not exceeding x) as in the conventional circuit.
