Abstract

The invention provides a bipolar input signal detection circuit. The bipolar input signal detection circuit comprises an input signal; a positive voltage detection module used for detecting a positivevoltage part of the input signal; a negative voltage detection module used for detecting a negative voltage part of the input signal; and a delay module used for delaying the detection result of thepositive voltage detection module or the detection result of the negative voltage detection module for a specified time, and performing OR operation on the detection result at the current moment and the delayed detection result to obtain an output level signal. According to the invention, through automatic bipolar detection, an effective control signal is output, and the design complexity is reduced.

Description

technical field [0001] The invention relates to the field of integrated circuit design, in particular to a bipolar input signal detection circuit. Background technique [0002] In a wired communication system, when the whole machine is not working, it is often hoped that the whole system is in a standby state, thereby reducing power consumption and prolonging the service life of the device. To enable the introduction of the transceiver, it is necessary to ensure that the transceiver is not working when the system is not working through manual operation or software configuration, so as to achieve the purpose of saving power consumption. However, software configuration through enabling will undoubtedly increase design complexity and greatly affect work efficiency. Contents of the invention [0003] In view of the above existing problems in the prior art, the present invention proposes a bipolar input signal detection circuit, which mainly solves the problem that the existin...
