I've been experimenting with digital thermal compensation on my GPSDO. The results have been favorable for a 14 bit dithered PWM-based DAC, but leaves a bit to be desired in the big picture. And it takes up a lot of program bytes on my PIC.. What's the general consensus on this? Should thermal compensation be completely analog?
Considering that time-constants can be fairly long, there is a benefit in having at least that part of the integrator in digital domain.
There are benefits of both approaches. Resolution of input and output can be a problem for the digital solution.
