Abstract
A linear reference analog to digital converter (ADC) network may include a first ADC operatively connected to a first sample and hold circuit. The linear reference ADC network may be configured to receive an input signal from the first sample and hold circuit and sample the input signal with a harmonic distortion. The linear reference ADC network may further include a reference ADC operatively connected to a second sample and hold circuit and configured to receive the input signal and sample the input signal with a second harmonic distortion. The linear reference ADC network may further include a combining module operatively connected to the first ADC and the reference ADC, the combining module configured to equalize a linearity of an output of the first ADC to a linearity of an output of the reference ADC, and output a combined output signal, and a circuit configured to output a calibrated output signal having calibrated harmonic distortion content.
