Abstract:
1. A low power receiver, comprising: an antenna comprising at least one antenna; a resonant circuit comprising at least one resonant circuit; a nonlinear device, wherein said antenna forms said resonant circuit or a part of said resonant circuit, or is directly or indirectly coupled to said resonant circuit, said antenna and said resonant circuit being tuned to receive a first high frequency carrier of a predetermined first frequency F wherein said low power receiver is configured to receive at least two pairs of high frequency carriers, and a frequency difference of said at least two pairs of high frequency carriers differ from each other, and wherein said low power receiver is further configured to generate two separate IF signals at different frequencies from said two pairs of high frequency carriers that represent two different data signals; and wherein said low power receiver is configured to be located within an implantable device configured to be implanted in a body of a mammal and wherein said implantable medical device is a pacemaker, a cardioverter/defibrillator, or a combination thereof.
