Abstract
A system is configured and a method is provided for receiving an input ratio represented by a first input signal and a second input signal, and producing an output ratio represented by a first output signal and a second output signal. The system is constructed and the method is provided for alternately operating in at least two time periods, wherein in one time period the first input signal, a low accuracy amplifier, and the first output signal are selectively coupled, and in another time period the input signal, the low accuracy amplifier, a high accuracy attenuator, and the second output signal are selectively coupled so as to maintain the output ratio proportional to the input ratio.
