摘要:
A regulator circuit includes an OP-amp, buffer, power transistor, voltage divider, load, and feedback current generator. The OP-amp generates first voltage signal by amplifying a difference between an input voltage signal and a feedback voltage signal. The OP-amp drives a first node as the first voltage signal. The buffer drives a second node as a second voltage signal generated based on the first voltage signal. The power transistor includes a drain terminal receiving a supply voltage, a gate terminal connected to the second node, and a source terminal connected to a third node. The voltage divider generates the feedback voltage signal by dividing an output voltage signal of the third node. The load includes a terminal connected to the third node and another terminal receiving a ground voltage. The feedback current generator provides a first feedback current corresponding to a ripple of the output voltage signal to the first node for enhancing a speed at which the ripple reduced.

摘要:
A method of determining a command line validity includes maintaining a block network address database including block network address information; receiving a command line from a terminal of a user; extracting network address information included in the command line; determining whether the network address information is the block network address information, with reference to the block network address database; generating log information associated with the command line in case that the network address information is not the block network address information as the result of the determination, in which the log information comprises at least one of the network address information included in the command line, input time point information with respect to the input time point of the command line, and request content information; recording the log information in a log database; and determining the validity of the command line by using the log information.
