Hi, I have a symmetric load 4 stage ring vco for simulation.Initially I try to simulate it by giving constant bias volatages at the PMOS bias and NMOS bias voltages. I do a transient analysis for observing the oscillation.But instead the simulation shows the two voltages stuck up at high (3.814V and 3.125V) for a 0.6um process. pmos bias volatge is 0.5V and NMOS as 2.5V. Thanks in advance, V
