Novel structure capable of automatically recognizing continuous signals and discontinuous signals

Abstract

The invention relates to a novel structure capable of automatically recognizing continuous signals and discontinuous signals. The novel structure comprises a signal collection and input module, a judgment module, a vibration module, a digital-to-analogue conversion module and a signal processing module, wherein the signal collection and input module is located outside a sensor signal collection chip and is used for inputting signals through a pin, and other modules are located in the sensor signal collection chip. In a working process, the signal collection and input module inputs the signals into the judgment module, the judgment module detects whether a vibration signal is in a port at set intervals, if n (n is more than 2) clk signals are detected, the digital-to-analogue conversion module is automatically turned off, and the vibration module is turned on; if no vibration signal is detected at the port, the vibration module is turned off, and the digital-to-analogue conversion module is turned on so as to convert the received continuous or discontinuous signals into corresponding control signals.

Description

technical field [0001] The invention relates to a novel structure capable of automatically identifying continuous signals and discontinuous signals, and belongs to the technical field of integrated circuits. Background technique [0002] In many occasions, it is often necessary to select continuous acquisition signals or intermittent acquisition signals according to specific environmental characteristics or consumer habits. For example, when the temperature sensor signal acquisition chip is working, sometimes it only needs to collect signals for several characteristic temperature points, and sometimes it needs to carry out continuous signal acquisition for a temperature segment. For example, when the headphone sensor signal acquisition chip is working, sometimes it only needs to collect a few fixed-frequency signals, and sometimes it needs to continuously collect signals of all frequencies. For another example, when the PM2.5 sensor signal acquisition chip is working and th...
