Abstract
A method and apparatus for modifying or controlling a resonator connected to a signal loop having an input, an output, and a closed loop frequency response. The signal loop has a primary resonator having a primary frequency response. There is at least one adjustable resonator having an adjustable frequency and a secondary Q-factor. An adjustable scaling block applies a gain factor. A controller is connected to the at least one adjustable resonator and the adjustable scaling block. The controller has instructions to adjust the closed loop frequency response toward a desired closed loop frequency response by controlling the adjustable frequency of the at least one adjustable resonator and the gain factor of the adjustable scaling block.
Claims15
A communications circuit, comprising:
- an antenna block that receives a desired electromagnetic signal;
- a signal loop comprising an input port, an output port, and a signal conditioning block between the input port and the output port, the antenna block being in bidirectional communication with the input port of the signal loop, wherein the signal conditioning block applies a phase shift and a gain factor to the desired signal;
- and
- a controller block that is configured to adjust the phase shift and the gain factor of the signal conditioning block to improve a signal quality factor of the desired signal from the antenna block.
