Abstract
An imaging pixel is provided. The imaging pixel includes a photodetector that outputs charge signals in response to incident light and laser pulses and a high-frequency path. A detector biasing circuit is further provided that biases high-frequency signals of the charge signals that are associated with the laser pulses to follow the high frequency path. The detector biasing circuit effectively filters low-frequency signal components of the charge signals from following the high-frequency path.
