I am running Phase Noise Analysis for an oscillating circuit structure (RF
Source). Problem is that each pair of neighboring pulses in the RF output
is asymmetric, meaning that for two consecutive pulses, peaks and lows are
not aligned and the scheme repeats as is. As a result, I have two
reference voltages (different but numerically close) for High and two for
Low.
Hence, when Phase Noise Analysis runs, each pair of these different pulses
are recognized by the simulator as one periodic signal and therefore
measured frequency is half of the actual.
Does anybody know how to adjust the internal Cadence tolerance when
comparing these neighboring pulses so that it measures the actual
frequency of the RF Signal and displays the correct Phase Noise
characteristics?
