Abstract

The invention provides a high-efficient two-wire system power modulation bus and an implementing method thereof, belonging to the field of electronic circuit. The modulation bus comprises two buses used for providing a power supply and a modulation signal, a sample circuit, a hysteretic feedback circuit, a low-pass filtering circuit and a signal comparator. The power modulation bus utilizes the hysteretic feedback circuit input into the signal comparator to realize following effect of the hysteretic feedback circuit by increasing hysteretic feedback voltage, so as to lead a power bus to have stronger capacity of resisting disturbance, lower error code rate and higher signal transmission rate when the data signal transmission is realized.

Description

technical field [0001] The invention belongs to the field of electronics and circuits. Background technique [0002] Utilizing a set of power lines to transmit power and digital communication signals at the same time is a very efficient way to set up circuits. But at present, the application of this technology is not very extensive. The main reason is that the current technology has many defects, mainly in poor anti-interference ability, high bit error rate, and low transmission rate. [0003] ginseng figure 1 As shown, this 11 shows the structural schematic diagram of the existing bus carrier demodulation circuit. It includes two bus sampling resistors, and the positive terminal of the comparator is connected to the sampling voltage of the bus, and the negative terminal is connected to the sampling voltage processed by the low-pass filter. [0004] The cut-off frequency of the low-pass filter is very low, and a large number of signals, including communication signals and...
