1. A circuit for down-converting an electromagnetic signal, comprising:

  • an energy transfer module and an energy storage module, said energy transfer module sampling the electromagnetic signal at an energy transfer rate to obtain sampled energy, said sampled energy being stored by said energy storage module, a down-converted signal being generated from said sampled energy, whereinsaid energy transfer module comprises;

    transistors coupled together, said transistors having a common first port, a common second port, and a common control port, wherein the electromagnetic signal is accepted at said common first port and said sampled energy is present at said common second port, and further wherein said common control port accepts a control signal, said control signal having a control frequency that is substantially equal to said energy transfer rate.
