Abstract: The disclosure relates to technology for generating multi-phase signals. An apparatus includes 2{circumflex over ( )}n phase signal generation stages. The apparatus also includes a controller configured to provide a mode input of each of the 2{circumflex over ( )}n stages with an active periodic binary signal with remaining inputs of each of the 2{circumflex over ( )}n stages provided with another periodic binary signal to collectively generate a 2{circumflex over ( )}n phase signal in a first mode. The controller is further configured to provide the mode input of each of 2{circumflex over ( )}(n−1) odd stages with a first steady state signal and the mode input of each of 2{circumflex over ( )}(n−1) even stages with a second steady state signal with remaining inputs of each of the 2{circumflex over ( )}n stages provided with the same periodic binary signal as in the first mode to cause either the 2{circumflex over ( )}(n−1) odd stages or the 2{circumflex over ( )}(n−1) even stages to collectively generate a 2{circumflex over ( )}(n−1) phase signal in a second mode.
