Ultra low power super-regenerative receiver and method thereof

An ultra low power super-regenerative receiver, comprising:

• a bit synchronizer configured to estimate a pulse-level position and a code-level position having a large correlation value using a plurality of samples included in a predetermined sliding window in a single period of a received symbol among samples taken in a signal output from a super-regenerative oscillator,
• a frame synchronizer configured to combine a plurality of pulse-level positions determined based on the estimated pulse-level position, and detect a predetermined bit sequence using the combined plurality of pulse-level positions, the frame synchronizer being configured to perform frame synchronization;
• and
• a data detector configured to detect data using the plurality of estimated pulse-level positions, after the frame synchronization is completed.

An ultra low power super-regenerative receiving method, comprising:

• estimating, using a value sampled from a signal output from a super-regenerative oscillator, a pulse-level position having a maximum amplitude value in a single period of a received symbol;
• combining a plurality of pulse-level positions determined based on the estimated pulse-level position;
• performing frame synchronization by detecting a predetermined bit sequence using the plurality of pulse-level positions combined;
• and
• detecting data using the plurality of pulse-level positions determined after the frame synchronization is completed.
