Abstract:
A signal sampling circuit includes: a signal output unit configured to output a level signal to an output node in response to a control signal; a signal sampling unit coupled to the output node and configured to sample the level signal in a sampling period; a first current sinking unit configured to sink a constant current from the output node; and a second current sinking unit configured to sink a current from the output node after a time point where the control signal is deactivated.
