Abstract
An encoder includes a linear offset amplifier, a linear analog to digital converter coupled to the linear offset amplifier, a switched offset amplifier, a switched analog to digital converter coupled to the switched offset amplifier, and a video controller. The video controller is coupled to both the linear and switched analog to digital converters. The video controller is configured to set both gains and offsets of the linear and switched analog to digital converters so that the gain and offset of the linear analog to digital converter is different than the gain and offset of the switched analog to digital converter.
