INPUT RECEIVER CIRCUIT

摘要

PURPOSE: An input receiver circuit is provided to enable a reference voltage to shift in an input margin improved direction based on a voltage level of input data. CONSTITUTION: An input receiver(200) comprises a voltage pull-up part(210) which increases a voltage level of a reference voltage(VREF) in response to a predetermined voltage level of input data(DIN). A differential amplifier(250) compares the input data with the reference voltage, and amplifies the voltage level of the input data according to a comparison result. The voltage pull-up part(210) includes a PMOS transistor(220) and a load(230).
