ABSTRACT:
According to some embodiments, a circuit includes a ring oscillator delay stage. The delay stage may include a first transistor, a second transistor, and an active inductor. A gate of the first transistor may receive a first input signal, a gate of the second transistor may receive a second input signal, a source of the second transistor may be coupled to a source of the first transistor, and the active inductor may be coupled to a drain of the first transistor.
