Abstract
A sampling circuit includes: a first input terminal, a second input terminal, a first voltage acquisition sub-circuit, and a current integrating sub-circuit. The first voltage acquisition sub-circuit is coupled to the first input terminal and the current integrating sub-circuit, and is configured to acquire a first voltage of the first input terminal and transmit the first voltage to the current integrating sub-circuit. The current integrating sub-circuit is further coupled to the second input terminal, and is configured to, generate and output a second voltage according to the first voltage and an integral of a driving current transmitted to the current integrating sub-circuit through the second input terminal over time, and output the first voltage in response to an integral control signal received by the current integrating sub-circuit.
