1. A biomodulation system comprising:
a non-implantable assembly configured to be worn by a subject, the non-implantable assembly comprising:
a power amplifier module configured to generate a wireless power signal; and an implantable assembly comprising:
at least one stimulation output;
at least one communication channel;
a control module operably connected to the at least one communication channel and the at least one stimulation output, the control module comprising a processor unit to process information sensed at acquisition circuitry via the at least one communication channel and, upon determining a condition exists, to generate at least one stimulation output via stimulation circuitry; and
a power management module configured to continuously generate one or more operating voltage for the implantable assembly using wireless power transfer from the non-implantable assembly, wherein the power management module generates two or more different operating voltages comprising one or more first operating voltages at a first voltage level and one or more second operating voltages having a second voltage level that is independent of the first voltage level, wherein the first operating voltages supplies the processor unit and the acquisition circuitry of the control module and wherein the second operating voltages supplies the stimulation circuitry of the control module.
