Abstract:
A voltage regulator for maintaining a voltage between a first node and a second node within a predetermined range, comprising:a. a transistor having a first pole electrically coupled to the first node, a second pole electrically coupled to the second node, and a gate;b. a first amplifier having a first input, a second input and an output; andc. a second amplifier having a first input, a second input and an output, wherein the first inputs of the first and second amplifiers are electrically coupled to the first node and the second inputs of the first and second amplifiers are electrically coupled to the second node so that the first and second amplifiers sense the same signal which represents the voltage between the first node and the second node, and the outputs of the first and second amplifiers are electrically coupled to the gate of the transistor, wherein the second amplifier is faster than the first amplifier responsive signal that is sensed.
