-Its detected current has few nA and few nV. And also there is voltage drop exist across diode. How this can work and play station without any external power source (battery)?
-What is the minimum and maximum level of current and voltage needed for crystal earphone to operate?
- Cannot we make FM receiver like this method?
Why?
Thanks in advance!
