Abstract: One example includes a VID signal decoder circuit. The circuit includes a coarse resolution decoder that receives a VID signal. The VID signal can be encoded with a digital value of an output voltage. The coarse resolution decoder can decode the VID signal to generate a first digital signal. The circuit also includes a fine resolution decoder that receives the VID signal and to decode the VID signal to generate a second digital signal. The circuit further includes a multiplexer to provide the first digital signal as an output signal responsive to a first state of a selection signal and to provide the second digital signal as the output signal responsive to a second state of the selection signal. The first and second states of the selection signal can be based on a relative amplitude of the first and second digital signals.
