Abstract
An imaging pixel including a control device to control flow of a charge signal from a photodetector. The control device has a variable impedance that varies in response to frequency of an input signal, the control device being biased to permit signals to flow through the control device dependent on the frequency of signals being output by the photodetector. The imaging pixel further includes a low-frequency signal path that receives a flow of signals that flow through the control device, and a high-frequency signal path independent of the low-frequency signal path and the control device, the high-frequency signal path receiving high-frequency signals included in the charge signal.
