Abstract
The present disclosure provides a super-regenerative transceiver with a feedback element having a controllable gain. The super-regenerative transceiver utilizes the controllable gain to improve RF signal data sensitivity and improve RF signal data capture rates. Super-regenerative transceivers described herein permit signal data capture over a broad range of frequencies and for a range of communication protocols. Super-regenerative transceivers described herein are tunable, consume very little power for operation and maintenance, and permit long term operation even when powered by very small power sources (e.g., coin batteries).
Claims22
An RF receiver comprising:
- two or more resonators, wherein each of the two or more resonators comprises two or more electrodes, wherein each of the two or more electrodes of a resonator is coupled to at least one other electrode of the two or more electrodes of the respective resonator;
- a feedback element coupled to at least one port, wherein the feedback element has one or more inputs to receive one or more feedback control signals to control a gain of the feedback element, the gain is controlled to change from a first value to a second value during a period of a single symbol, the gain is a loop gain, the first value corresponds to the loop gain being zero or less, and the second value corresponds to the loop gain being 1 or more;
- and
- a switch configured to couple each of the at least one port to at least one of the two or more electrodes of an active resonator, wherein the active resonator is selected from the two or more resonators based at least in part upon one or more resonator select signals.
A system to capture symbol data from a wireless signal using an RF receiver, the system comprising:
- two or more resonators, wherein each of the two or more resonators comprises two or more electrodes, wherein each of the two or more electrodes of a resonator is coupled to at least one other electrode of the two or more electrodes of the respective resonator;
- a feedback element coupled to at least one port, wherein the feedback element has a gain, and the gain is controlled based at least in part upon one or more feedback control signals;
- a switch configured to couple each of the at least one port to at least one of the two or more electrodes of an active resonator, wherein the active resonator is selected from the two or more resonators based at least in part upon one or more resonator select signals;
- one or more processors;
- and
- one or more memories operatively coupled to at least one of the one or more processors and having instructions stored thereon that, when executed by at least one of the one or more processors, cause the system to:
- provide instructions to select a first resonator of the two or more resonators as the active resonator, wherein the first resonator is selected as the active resonator based at least in part upon at least one of the one or more resonator select signals comprising first data;
- provide instructions to set the gain to a first value during a first portion of a period of a single symbol, wherein the gain is set based at least in part upon at least one of the one or more feedback control signals comprising second data;
- and
- provide instructions to set the gain to a second value during a second portion of the period of the single symbol, wherein the gain is set based at least in part upon at least one of the one or more feedback control signals comprising third data.
A computer-implemented method of capturing symbol data from a wireless signal using an RF receiver, wherein the RF receiver comprises two or more resonators, a feedback element, and a switch, each of the two or more resonators comprises two or more electrodes, each of the two or more electrodes of a resonator is coupled to at least one other electrode of the two or more electrodes of the respective resonator, the feedback element is coupled to at least one port, the feedback element has a gain, the gain is controlled based at least in part upon one or more feedback control signals, the switch is configured to couple each of the at least one port to at least one of the two or more electrodes of an active resonator, and the active resonator is selected from the two or more resonators based at least in part upon one or more resonator select signals, the method comprising:
- providing, by at least one of one or more processors, instructions to select a first resonator of the two or more resonators as the active resonator, wherein the first resonator is selected as the active resonator based at least in part upon at least one of the one or more resonator select signals comprising first data;
