Method of designing a multi-channel micro-electrical stimulation with an equivalent current source that works with an adiabatic baseband based on direct-carrier energy extraction

A method of designing a multi-channel micro-electrical stimulation structure with an equivalent current source that works with an adiabatic baseband based on direct-carrier energy extraction, comprising steps below:

• a. a method of design of the equivalent current source being applied to implement a stimulation array;
• b. the stimulation array carrying out stimulation in each channel and giving a set of stimulation control signals so as to adjust the cumulative charge of stimulation by means of proper electrical stimulation strength through a time sequence axis;
• c. a digital baseband circuitry being arranged at a demodulation signal receiving end, and after the modulation signal of carried stimulation control information is demodulated, clock extraction being executed and the stimulation control signals being processed;
• d. an adiabatic design being applied to significantly reduce the power required by the digital baseband circuitry in the aspect of switching current, and a design cost of extra voltage regulator circuit being reduced;
• and
• e. a method of direct carrier being applied to extract the power required by the digital baseband circuitry, in which a carrier signal coupled into a receiver coil, through an input matching and a step voltage drop circuit, is fed into a pair of dual circuits to extract the complementary energies required by the subsequent digital baseband circuitry.
