I am not quite sure weather I should put this question in this part or not, it’s partly digital and partly analogue, I am looking forward to design a variable inductor and a variable capacitor, i.e. I want to have a variable inductor and a variable capacitor whose values could be adjusted by the data from microcontroller. Price is not a factor in this design, but board space and relative simplicity is my main concern. I was originally thinking of using a number of separate fixed value inductors and capacitors which could be selected by the microcontroller via some analogue switches, but this will certainly take up a lot of board space and is virtually impractical. Any ideas? Any hints as to where I should start from?
