A semiconductor circuit and a method of operating the same are provided. The semiconductor circuit comprises a first digital-to-analog converter configured to generate a first output current in response to a first binary code, and a second digital-to-analog converter configured to generate a second output current in response to a second binary code associated with the first binary code. The semiconductor circuit further comprises a first current-to-voltage converter configured to generate a first candidate voltage based on the first output current, and a second current-to-voltage converter configured to generate a second candidate voltage based on the second output current. The semiconductor circuit further comprises a multiplexer configured to output the target voltage based on the first candidate voltage or the second candidate voltage. The target voltage includes a configurable range associated with the second binary code.
