Abstract
In accordance with some embodiments of the present disclosure, a circuit comprises an input node configured to receive a current-mode input signal and an input stage that includes an input device communicatively coupled to the input node. The input device is configured to receive the input signal at the input node. The circuit additionally comprises bias circuitry communicatively coupled to the input stage and configured to provide a bias current for the input device. The bias circuitry is also configured to remove at least a portion of the bias current from the input signal through a feedback loop associated with the input node such that the input signal is received by the input device with at least a portion of the bias current removed. The circuit further comprises an output stage communicatively coupled to the input stage and configured to output a current-mode output signal based on the input signal.
