FAST TRANSIENT RESPONSE VOLTAGE REGULATOR

摘要

Techniques are described for adjusting an amount of current flowing through a first and second transistor of a voltage regulator connected to an output of a voltage regulator to maintain an output of the voltage regulator at a constant output voltage level. Also, a resistor connects a gate of the first transistor to a gate of a second transistor. The techniques may also charge or discharge a parasitic capacitance of the first transistor with a first current source connected to the gate of the first transistor and a second current source connected to the gate of the first transistor through the resistor.
