Provided are a reference source circuit, a chip, a power supply, and an electronic device. The circuit comprises: a first current generation unit used for generating first current; a reference voltage generation unit electrically connected to the first current generation unit and used for generating a band-gap reference voltage by using the first current; and a reference current generation unit electrically connected to the first current generation unit and the reference voltage generation unit and used for generating band-gap reference current by using the first current. By means of the circuit above, a band-gap reference voltage and band-gap reference current can be generated in a reference source circuit, and the first current generation unit may be reused, so that high-gain and simultaneous work of two loops can be achieved, the cost can be reduced, and the chip area can be saved as compared with the design of two separate reference sources.

Reference source circuit, chip, power supply, and electronic apparatus

A single-wire transmission method, a chip and a communication system are disclosed, wherein the single-wire transmission method comprises: receiving X sets of data to be transmitted, a trigger flag before each set of data to be transmitted and an end flag after each set of data to be transmitted through a single line, wherein X is a positive integer greater than 0, and each set of data to be transmitted is represented by the number of transition edges; confirming the trigger flag; counting the transition edge after confirming the trigger flag to obtain a number of the transition edges, performing a decoding process according to the number of the transition edges until the end flag is received, wherein the transition edges are recounted and the decoding process is re-performed after the end flag is received each time. The data transmission time is shorter, which improves the data transmission efficiency.
