Abstract

Systems and methods for utilizing universal frequency translators within gated energy transfer systems for phase detection and/or frequency detection. Phase and/or frequency detection can be utilized for comparing a higher frequency reference signal with a lower frequency local oscillator signal. Phase and/or frequency detection can also be utilized for phase locking and/or frequency locking. The systems and methods can be utilized to simultaneously downconvert a reference signal for phase and/or frequency comparison and/or for locking, at lower Phase and/or frequency detection can be utilized for frequencies, which is easier to design and which requires less expensive electrical components.

Claims

1. A circuit, comprising:

a switch that sub-samples and transfers energy from a first signal; and

a storage device, coupled to said switch, that stores said transferred energy, wherein a second signal is generated from said first signal, and wherein a frequency of said second signal differs from a frequency of said first signal.
