ABSTRACT:
A CMOS current mirror is provided that includes a current input, an input transistor, whose conductivity path is located between the current input and a reference potential terminal, a current output, an output transistor, whose conductivity path is connected to the reference potential terminal and which supplies the current output with an output current, a gate node common for both transistors, and a supply potential terminal. The current mirror further includes a first additional transistor, whose conductivity path is located between the supply potential terminal and the gate node and whose gate terminal is connected to the current input, and a second additional transistor, whose conductivity path is located between the gate node and the reference potential terminal and whose gate terminal is connected to the gate node.
