Dear all,

I have some problem about simulating an oscillator.

My oscillator has no voltage/current pulses to start up,

it just takes a while before the output signals growth

and stabilized. But, surprisingly, when I applied a

voltage pulse as the supply voltage, the oscillator does

not work !!!!

------------ My problems are: ---------------

- In SpectreRF simulation, how should I start an

oscillator and can be sure that it will work in reallity ?

- I found that, in PSS simulation, SpectreRF does not

allow using any voltage/current pulse in a circuit. So,

how could I start it up ???

Thank you all in advace,

Alez

As a further note, you can apply an impulse with a pulse source - just don't specify the period. That way the source is then a one-shot and not periodic. You can't have periodic sources when you're using PSS in autonomous mode.

Regards,

Andrew.
