Abstract: In an example, an apparatus includes a first decoder circuit having a first voltage identification (VID) analog input and a first digital output. The apparatus also includes a precharge circuit having a digital input and a first analog output, the digital input coupled to the first digital output. The apparatus also includes a second decoder circuit having a second VID analog input, a precharge analog input and a second digital output, the precharge analog input coupled to the first digital output. The apparatus also includes a multiplexer having a multiplexer output and first and second multiplexer inputs, the first multiplexer input coupled to the first digital output, and the second multiplexer input coupled to the second digital output.

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.
