Abstract

An inverting stage is coupled between a single-ended in-put node and a first differential output node, and a non-inverting stage is coupled between the single-ended input node and a second differential output node. The inverting stage includes at least one transistor with a first current terminal, a second current terminal, and a control terminal, the first current terminal being coupled to the first differential output node and the control terminal being coupled to a single-ended input node. The non-inverting stage includes at least one transistor with a first current terminal, a second current terminal, and a control terminal, the first current terminal being coupled to the second differential output node, and the second terminal being coupled to the single-ended input node. A bias current of the inverting stage is larger than a bias current of the non-inverting stage.
