I have a system designed (calculated and simulated) and a couple of PCB designs.
This system/project is to ensure good-excellent magnetic coupling efficiency between receiving and transmitting coils and test a pulse-width modulated amplitude shift keying modulation and ensure minimal interference from neighboring coils. Also the effect of a major component L1, which is a choke inductor
we are interested in a multiple spiral inductor coil structure, with PWM-ASK modulation, that has a rise and fall when switching between amplitude states.
there are future designs that needs testing, so if done well, more jobs will be opened.
I have attached a zip file containing the following:
a file describing the PWM-ASK and its effeciency.
a file with the formulas of the class-E amplifer
a file describing the rise and fall when switching amplitudes.
an m-file calculates the dimension of a spiral coil, for an inductor
an m-file calculates the class-E amplifer components.
