Technical Examples

Systems and techniques for converting an analog input signal to a digital code are described. A system includes a differential stage to produce a sign bit indicative of a sign of the analog input signal and to generate a first analog signal that is approximately equal to an absolute value of the analog input signal. The system also includes an analog-to-digital converter (ADC) to convert the first analog signal to a second digital code representing a magnitude of the analog input signal and a controller to combine the second digital code and the sign bit to produce a first digital code.
