BANDGAP REFERENCE VOLTAGE GENAERATING CIRCUIT FOR GENERATING BANDGAP REFERENCE VOLTAGE SATABLE REGARDLESS OF DEVIATION IN FABRICATION CONDITION

摘要

band-gap reference voltage generating circuit for generating a stable bandgap reference to a change in process conditions is disclosed . The band gap reference voltage generation circuit of the present invention is a band gap voltage generator for generating a bandgap reference voltage, the level of the band gap reference voltage is the band gap voltage generation section is controlled by the level control data; Performs a level adjustment in accordance with the capacitance of the capacitor group monitoring controlled by the capacitance setting data, charge monitoring unit for generating a monitoring signal indicative of a result of monitoring the level adjustment; And in response to the clock signal group, as a continuous data storage unit for generating the level control data and the capacitance setting data, the level control data corresponding to the capacitance setting data transition is generated in one direction of the logical state of the monitoring signal which comprises the successive parts of information stored with a data value. According to the band-gap reference voltage generating circuit of the present invention, a stable bandgap reference to a change in process conditions (VBGR) is provided.
