Abstract

See full text

A device includes a first transistor coupled to a ground node and a current source. The first transistor includes a control terminal coupled to a reference voltage source, where the current source is coupled to an input voltage source. The device includes a second transistor coupled to the input voltage source, where the second transistor includes a control terminal coupled to the first transistor. The device includes a third transistor coupled to the second transistor, where the third transistor includes a control terminal coupled to an output voltage node. The device includes a fourth transistor coupled to the third transistor, where the fourth transistor includes a control terminal coupled to the output voltage node. The device includes a fifth transistor coupled to the fourth transistor and a resistor, where the fifth transistor includes a control terminal coupled to the fourth transistor. The resistor is coupled to the ground node.
