Research of weak signal detection based on super‐regenerative chaotic oscillator
Electronics Letters, 2022 Under certain circumstances, chaos will occur in the super‐regenerative receiver. The gain of the receiver reaches the maximum and the receiver is immune to the external noise in this case. The concept of super‐regenerative chaotic oscillator is proposed,
