VOLTAGE GENERATING APPARATUS HAVING HIGH SPEED CHARGING AMPLIFIER AND LOW SPEED DISCHARGING AMPLIFIER, ESPECIALLY OBTAINING RAPID TRANSIENT RESPONSE CHARACTERISTIC

摘要

PURPOSE: A voltage generating apparatus having a high speed charging amplifier and a low speed charging amplifier is provided to accelerate a transient response characteristic by implementing at least one high speed charger in a push-pull amplifier of the voltage generating apparatus. CONSTITUTION: A voltage generating apparatus has an input terminal, an output terminal, a low speed discharging amplifier(11N) connected between the input terminal and the output terminal, a high speed charging amplifier(11p) connected between the input terminal and the output terminal, and a first offset voltage generating element(r1). The low speed discharging amplifier is connected between the input terminal and the output terminal. The high speed charging amplifier is connected between the input terminal and the output terminal. The first offset voltage generating element is connected between the input terminal and one of the low speed discharging amplifier and the high speed charging amplifier, such that an input voltage applied to the low speed discharging amplifier is higher than an input voltage applied to the high speed charging amplifier.
