Abstract
An imaging pixel includes a photodetector for generating a charge signal, an input buffer, a control device, and a switch. The input buffer is connected to the photodetector for amplifying the charge signal. The control device is connected to the photodetector and the input buffer to separate high-frequency charge signals from low frequency charge signals. The switch is operably connected to the input buffer for sampling of high-frequency charge signals in a charge storage device triggered by amplitude of high-frequency charge signals provided by the input buffer.
