Disclosed in an interface circuit, in which: a current input circuit receives an input current signal of a signal input terminal, an input voltage detection circuit compares an input voltage signal of the signal input terminal with a reference voltage, and provides a detection signal to the current input circuit according to the comparison result, a phase-inversion output circuit is connected with the current input circuit at the first node, and generates a voltage conversion signal according to a voltage potential of the first node, and a buffer circuit performs signal shaping on the voltage conversion signal to obtain an output signal. The current input circuit pulls up the voltage potential of the first node when the detection signal indicates that the input voltage signal is greater than the reference voltage and the input current signal is greater than a reference current.

Interface circuit

Disclosed are a switching converter and an oscillator thereof. The oscillator includes a charging current generating circuit and a clock signal generator circuit, which is used for generating a clock signal according to a charging current provided by the charging current generating circuit. The charging current generating circuit includes a variable resistor and a current limiting module. The current limiting module is used for limiting a current value of the charging current to a preset current value when the variable resistor is shorted or opened, thus avoiding drastic change of a switching frequency of the circuit when the external variable resistor is shorted or opened, so as to improve system stability.

Switching converter and oscillator thereof

An entity recognition method and apparatus, an electronic device, a storage medium, and a computer program product are provided. The method includes: recognizing a to-be-recognized image to determine a preliminary recognition result for entities in the to-be-recognized image; determining, in response to determining that the preliminary recognition result includes a plurality of entities of a same category, image features of the to-be-recognized image and textual features of the plurality of entities; determining whether the plurality of entities is a consecutive complete entity based on the image features and the textual features, to obtain a complete-entity determining result; and obtaining a final recognition result based on the preliminary recognition result and the complete-entity determining result.

Entity recognition method and apparatus, and computer program product
