PIXEL SENSOR WITH COMBINED LIGHT TO FREQUENCY AND LIGTH TO TIME ANALOGUE DIGITAL CONVERSION

摘要

Light is converted to an electric signal by performing a light-to-frequency conversion of the light received during a first phase of operation. Following the first phase of operation, a light-to-time conversion is performed on light received during a second phase of operation. Following the second phase of operation a digital representation of the light is generated in response to the light-to-frequency conversion and the light-to-time conversion.
