    Large Variable Capacitor

    Thanks for your response, Laplace. So far I haven't found mechanical capacitors with plates that are large enough. I think this is because they have air dielectrics to allow them to move freely. The digital switching approach is certainly a viable option. Another thought I had was to cascade...

    Large Variable Capacitor

    Does anyone know how to create a variable capacitor that can be actively controlled between say 1nF and 1uF? The three types of variable capacitors (digital switched, mechanical rotary, and varicap diode) all seem to be limited to the pF range of capacitance. Any creative ideas to make much...
