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).
Claims28
An RF receiver comprising:
- a resonator comprising two or more electrodes, wherein each of the two or more electrodes is coupled to at least one other electrode of the two or more electrodes, and the two or more electrodes comprise at least one feedback electrode;
- and
- a feedback element coupled to the at least one feedback electrode, 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, and the gain is controlled to change from a first value to a second value through at least one intermediate value during a period of a single symbol based at least in part upon the one or more feedback control signals.
A system to capture symbol data from a wireless signal using an RF receiver, the system comprising:
- a resonator comprising two or more electrodes, wherein each of the two or more electrodes is coupled to at least one other electrode of the two or more electrodes, and the two or more electrodes comprise at least one feedback electrode;
- a feedback element coupled to the at least one feedback electrode, wherein the feedback element has a gain, and the gain is controlled based at least in part upon one or more feedback control 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 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 first data;
- provide instructions to set the gain to an intermediate 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 second data, and the intermediate value is between the first value and a second value;
- and
- provide instructions to set the gain to the second value during a third 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 a resonator and a feedback element, the resonator comprises two or more electrodes, each of the two or more electrodes is coupled to at least one other electrode of the two or more electrodes, the two or more electrodes comprise at least one feedback electrode, the feedback element is coupled to the at least one feedback electrode, the feedback element has a gain, and the gain is controlled based at least in part upon one or more feedback control signals, the method comprising:
- providing, by at least one of one or more processors, 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 the at least one of the one or more feedback control signals comprising first data;
- providing, by at least one of the one or more processors, instructions to set the gain to an intermediate 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 second data, and the intermediate value is between the first value and a second value;
- and
- providing, by at least one of the one or more processors, instructions to set the gain to the second value during a third 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.
