Abstract
An integrated circuit includes a first stage configured to receive a bias current. A current regulation loop includes a transimpedance amplifier having a first transistor, and a second transistor having a gate coupled to a gate of the first transistor. The first transistor and the second transistor are configured to compare the bias current with a reference current, and to generate a regulation voltage on an output node of the transimpedance amplifier. A capacitor is coupled between the output node of the transimpedance amplifier and the gates of the first and second transistors.
