Thanks for all your reply!
To clarify a few points:
Actually I have tried both the maneatis and the diode loaded delay cell. However, both of them would only oscillate when there are at least three stages. In order to make the Ring oscillator oscillate at 2 stages, some positive feedback mechanisms have to be introduced, for example, a cross-coupled latch. However, in this way, the osc will saturate and that is the tricky point. So what I am looking for is the delay cell that can introduce at least the 90 degree of phase shift in order to oscillate while without using latch in order to be unsaturated. Sound contradictory, ur
BTW, this is a research project, so the specs might not make any sense from the practical point of view.
