Abstract
A circuit for sensing and amplifying a signal of a signal line includes a sensing voltage generation circuit including a sensing circuit, the sensing voltage generation circuit configured to generate a sensing voltage by sensing and amplifying a line input signal based on a bias voltage, and a bias voltage generation circuit including a replication circuit, the replication circuit having a structure identical to a structure of the sensing circuit and generating a replication voltage and the bias voltage generation circuit configured to generate the bias voltage by comparing the replication voltage with a logic threshold level.
