Abstract:

A voltage follower circuit including an input stage for generating a difference between the input signal and the output signal. An output circuit receiving the first signal and producing the output signal. A slew boost circuit includes a first transistor having a control electrode for receiving the input signal, a first electrode coupled to a first current source, and a second electrode coupled to a first supply voltage, a second transistor having a control electrode coupled to the first electrode of the first transistor, a first electrode coupled to the first signal, and a second electrode coupled to the first supply voltage, and a third transistor having a control electrode coupled to the first electrode of the first transistor, a first electrode coupled to the first signal, and a second electrode coupled to a second supply voltage.
