Embodiment Construction

[0039] Such as figure 1The shown adaptive burst signal receiving regenerative amplifier, wherein 1 and 2 are the input terminals of two differential complementary burst signals, 1 is positive phase input, 2 is negative phase input, and two larger coupling capacitors 3, 4 The capacity is equal, and the two input terminals are respectively connected to form a symmetrical larger AC coupling constant with the input impedance of the subsequent stage, so that the input signal is AC-coupled to the next-stage circuit.

[0040] The effect of input signal control circuit 5 is to make small signal pass through with 0dB gain, and to large signal attenuation, to avoid large signal to cause rear stage circuit input overload, reduce large signal distortion, increase the input signal of burst signal receiving regenerative amplifier of the present invention Dynamic Range.

[0041] The capacity of the two equal capacitors 6 and 7 is sufficiently small, and the two equal resistors 8 and 9 are a...

Abstract

The invention provides a self-adapting burst-mode signal receiving and regenerating amplifier, relating to the technical field of digital communication. The prior art has the defects of low receiving sensitivity and no self-adapting capability. The amplifier of the invention comprises an AC coupling circuit, a high-pass filtering circuit and a positive feedback amplifying circuit. By combining a series of high and low pass filters and a multistage amplifier, the bit-by-bit recovery of burst-mode signals is realized, and the receiving sensitivity is improved. The whole processes of input, amplification, regeneration and output of signals are automatically finished. The invention has perfect self-adapting functions.

Description

technical field [0001] The invention relates to the technical field of digital communication, in particular to a burst signal receiving regenerative amplifier with perfect self-adaptive function. It amplifies the input burst digital voltage signal stream, so that the burst signal can be regenerated at the output of the burst regenerative amplifier, that is, the level and phase relationship of all bits of the output signal stream can be processed by subsequent digital processing circuits or modules. correctly identified. Background technique [0002] Since the invention of digital communication, the transmission of burst digital signals, whether it is optical transmission or electrical transmission, has been a major problem. The reason why it has become a problem is that the burst signal reception and regeneration amplifier (Regeneration Amplifier) ​​are difficult to realize. The traditional digital transmission technology is to process the original source signal with burst ...
