Methods and systems for down-converting a signal using a complementary transistor structure
First Claim
1. A circuit that down-converts a first signal to produce a lower frequency second signal, comprising:
- a pulse generator to generate a control signal including a plurality of pulses, each pulse of the plurality of pulses having an aperture; and
an energy transfer module to sub-sample the first signal to transfer energy therefrom;
wherein the energy transfer module includes a complementary transistor structure and is controlled by the control signal.

Abstract
Methods, systems, and apparatuses for down-converting an electromagnetic (EM) signal by aliasing the EM signal are described herein. Briefly stated, such methods, systems, and apparatuses operate by receiving an EM signal and an aliasing signal having an aliasing rate. The EM signal is aliased according to the aliasing signal to down-convert the EM signal. The term aliasing, as used herein, refers to both down-converting an EM signal by under-sampling the EM signal at an aliasing rate, and down-converting an EM signal by transferring energy from the EM signal at the aliasing rate. In an embodiment, the EM signal is down-converted to an intermediate frequency (IF) signal. In another embodiment, the EM signal is down-converted to a demodulated baseband information signal. In another embodiment, the EM signal is a frequency modulated (FM) signal, which is down-converted to a non-FM signal, such as a phase modulated (PM) signal or an amplitude modulated (AM) signal.
