Abstract
Embodiments relate to programmable delay circuit. An aspect includes a first stage comprising a first hybrid fin field effect transistor (finFET) comprising a first gate corresponding to a first control FET, and a second gate corresponding to a first default FET, and a first plurality of fins, wherein the first gate and the second gate of the first stage each partially control a first shared fin of the first plurality of fins. Another aspect includes a second stage connected in series with the first stage, the second stage comprising a second hybrid finFET comprising a first gate corresponding to a second control FET, and a second gate corresponding to a second default FET, and a second plurality of fins, wherein the first gate and the second gate of the second stage each partially control a second shared fin of the second plurality of fins.
