Abstract :
The recently proposed split analog-to-digital converter (ADC) owes its advantages to the quantization noise from its constituent analog delta-sigma modulators being uniformly distributed, white, and uncorrelated with the input and with each other. A theoretical analysis of the statistics of the quantization noise is presented in the context of a generic split-ADC. Sufficient conditions are derived that ensure that the quantization noise has the aforementioned properties; the application of the conditions is illustrated in the case of two example split-ADCs
