Patent ID: 8593221

Claim:
A current generator circuit to provide a first output current and a second output current comprising: a first transistor including a first, second, and third terminal, the first transistor configured to provide the first output current at the third terminal of the first transistor; a second transistor including a first, second, and third terminal, the second transistor configured to provide the second output current at the third terminal of the second transistor; a first branch including a first resistor and a first capacitor coupled in series, the first branch coupled between the third terminal of the first transistor and the first terminal of the second transistor; and a second branch including a second resistor and a second capacitor coupled in series, the second branch coupled between the third terminal of the second transistor and the first terminal of the first transistor, wherein the first and the second branches are configured to enable the current generator circuit to provide the first and second output currents with an improved common mode stability including an associated common mode stability factor that is greater than one over a substantially wide frequency range.
