It is true that RF circuits come with their own challenges. They operate at high frequency and large dynamic range. They are vulnerable to parasitics, bond wires and packages and have tough requirements on noise and linearity. However, none of these challenges called for a special simulation technology. Periodic Steady State and Envelope analysis were developed to exploit another key feature of RF circuits: their periodic nature. RF circuits process very fast periodic signals such as a carrier or a local oscillator together with slow analog signals at baseband frequency. This situation is not limited to RF applications. A big group of analog circuits such as power management circuits, switched cap filters, switched mode power supplies process slow data signals in the presence of a fast periodic signal, the clock. Can these circuits also benefit from Periodic Steady State and Envelope analysis?
If you design power management circuits, power supplies, switched capacitor circuits or any other analog circuits that process analog data in the presence of a fast clock, then I'd like to invite you to the first webinar of our Analog Smart webinar series. In this webinar, analog simulation expert Art Schaldenbrand will teach you how RF simulation technologies can help you speed up your simulations without the slightest compromise of accuracy. This first webinar scheduled for next Monday will focus on DC-to-DC converters.

I am glad that Cadence is finally addressing this subject (see my earlier comments at www.cadence.com/.../spectre-rf-by-any-other-name.aspx for some possible applications).
The recorded webinar is available at www.cadence.com/.../event.aspx (registration required).
