BOOSTING VOLTAGE GENERATING CIRCUIT SHARING AN OUTPUT VOLTAGE OF EACH BOOSTING UNIT

摘要

PURPOSE: A boosting voltage generating circuit is provided to stably operate an integrated circuit by reducing a boosting speed difference between charge bumps.;CONSTITUTION: A first voltage boosting unit(210) generates a first output voltage. A second voltage boosting unit(220) generates a second output voltage. A control unit(300) activates a control signal if the first output voltage dose not reach a first critical value and if the second output voltage dose not reach a second critical value. A connection unit(400) includes a connection unit which connects an output terminal of the first voltage boosting unit and an output terminal of the second voltage boosting unit when the control signal is activated.;COPYRIGHT KIPO 2013;[Reference numerals] (210) First voltage boosting unit; (220) Second voltage boosting unit; (300) Control unit; (400) Connection unit
