    Hi,

    For my project I need to design an inductive coupling circuit for 2 devices to communicate. However, upon trying to design the class D amplifier, I've come across issues that has put a stop to my designing.

    I want to design a class D amplifier to amplifier and transmit power to the remote device. The problem is i'm not sure what sort of gate driver would i need to efficiently turn on and off the JFET N-channel transistors. I'm currently using a Dual voltage transformer and an astable circuit. The filter design consists off course of a inductor and capacitor. But i would like to use the inductor as the transmission coil.

    How would I go about doing this?

    Thank you

    A 555 10Mhz Astable? You have bigger problems, a standard 555 stops at 1Mhz, and a TLC555 (TI CMOS 555) rolls of at 2Mhz.
