Abstract
The present disclosure provides for an analog-to-digital converter (ADC) which selectively compresses an analog input signal to improve noise performance and dynamic input range. The ADC selectively scales an analog input signal when it is closer to an expected value of one or more signal metrics more than when it is further from the expected value of the one or more signal metrics. For example, during the conversion process, the ADC amplifies the analog input signal when it is closer to a mean value μ by a gain factor while selectively adjusting the gain factor when the analog input signal is further from its mean value μ to selectively compress the analog input signal. This selective compression improves input noise performance and dynamic input range of the ADC when compared to the conventional ADC.
