Abstract
Official abstract text for this publication.
Provided are an amplifier circuit capable of improving phase characteristics, and a voltage regulator including the amplifier circuit. The amplifier circuit is configured to amplify an input voltage and to output the input voltage, and includes a current source, a first transistor having a gate to which the input voltage is applied, and a second transistor having a gate to which a voltage synchronous with the input voltage is applied, and a source connected to a capacitor.
First claim
Opening claim text (preview).
What is claimed is: 1. An amplifier circuit, which is configured to amplify a voltage input to an input terminal and to output the amplified voltage to an output terminal, the amplifier circuit comprising: a current source; a first transistor including a gate connected to the input terminal; a second transistor including a drain connected to the current source, a source connected to the drain of the first transistor, and a gate connected to the input terminal; and a capacitor including one terminal connected to the source of the second transistor, the drain of the second transistor being connected to the output terminal. 2. An amplifier circuit according to claim 1 , wherein the current source comprises a resistor element. 3. An amplifier circuit according to claim 1 , further comprising a voltage source on another-terminal side of the capacitor. 4. An amplifier circuit according to claim 1 , further comprising a resistor element, which is connected to the capacitor in series. 5. An amplifier circuit according to claim 1 , further comprising a voltage source between the gate of the first transistor and the gate of the second transistor. 6. A voltage regulator, comprising the amplifier circuit of claim 1 .
