Patent ID: 7898336

Claim:
An output stage, comprising: a current controller ( 110 ), that operates in accordance with the translinear principle, including a first input (in 1 ), a second input (in 2 ) and an output; a current mirror ( 120 ) including an input and an output; and an output transistor (Q 5 ) including a control terminal and a current path including a first terminal and a second terminal; wherein the control terminal of the output transistor (Q 5 ) forms an input of the output stage; wherein the first current path terminal of the output transistor (Q 5 ) is connected to the second input (in 2 ) of the current controller ( 110 ); wherein the second current path terminal of the output transistor (Q 5 ) forms an output of the output stage, and is connected to the output of the current mirror ( 120 ); wherein the first input (in 1 ) of the current controller ( 110 ) is connected to a bias current source (Ibias); and wherein the output of the current controller ( 110 ) is connected to the input of the current mirror ( 120 ).
