Abstract

The embodiment of the invention discloses a chip pin circuit, which comprises a chip pin, a reference voltage circuit and a comparison circuit. The comparison circuit comprises a plurality of comparators, each comparator is connected with the chip pin and receives a first signal from the chip pin, the reference voltage circuit generates a plurality of reference voltages and outputs the reference voltages to the corresponding comparators respectively, one comparator compares the first signal with the reference voltages, generates a first control signal and transmits the first control signal to a chip internal circuit and the other comparator, and the chip internal circuit and the other comparator are controlled. According to the chip pin circuit provided by the embodiment of the invention, after the chip pin receives the signal, only part of the comparison circuit is started to receive and convert the signal, so that the purpose of saving power consumption is achieved.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a chip pin circuit, a chip and a device including the same. Background technique [0002] With the development of information technology, more and more functions need to be integrated on the chip, more digital control signals or analog signals need to be received and converted, and the number of pins of the chip is also increasing. Power consumption is also increasing. Contents of the invention [0003] The problem solved by the invention is to achieve the purpose of saving power consumption while not affecting the receiving signal and converting signal of the chip pin circuit. [0004] In order to solve the above problems, an embodiment of the present invention provides a chip pin circuit, which includes: a chip pin, a reference voltage circuit, and a comparison circuit, wherein the comparison circuit includes a plurality of comparators, and each of the comparator...
