Abstract
Disclosed herein is a signal processing circuit including: a main path configured to transmit an input signal and output an actual signal; and a negative feedback path configured to feed back the actual signal to an input stage of the main path, wherein the main path includes a main path block that receives an input signal and outputs an actual signal, the negative feedback path includes a negative feedback block that generates a control signal and supplies the control signal to an input part of an input signal of the main path; a replica block that is supplied with a control signal of the negative feedback block to output a pseudo actual signal, and imitates the main path block; and a signal delay block that delays a pseudo actual signal of the replica block by a dead time of a loop.
