Abstract
Examples of circuits and methods are provided for common mode stability and bandwidth broadening. A current generator circuit may include a first and a second transistor. Each of the first and second transistors includes a first, second, and third terminal. The first and second transistors provide a first and a second output current at their corresponding third terminals. A first branch including a first resistor and a first capacitor coupled in series is coupled between the third terminal of the first transistor and the first terminal of the second transistor. A second branch including a second resistor and a second capacitor coupled in series is coupled between the third terminal of the second transistor and the first terminal of the first transistor. The first and the second branches are configured to enable the current generator circuit to provide the first and second currents with improved common mode stability.
