I recently found an article describing how to create an analog output from a pic. The article discusses sending a pulse to a cap and monitoring the charge with an A/D. The link for the article is below:

I thought this was a neat idea and could be more accurate than using normal PWM to produce an analog output. Has anyone put together a circuit similar to this?
