Parallel analog to digital converted (ADC) architectures that can be used to replace single path ADC architectures. The parallel ADC architecture can comprise N branches and one ADC per branch. These ADCs can be identical. However each branch can have a different path adjustments applied to the ADC. The path adjustments can be biases and/or gains and each ADC receives a different combination of biases and/or gain to generate multiple adjusted input signals. These are then combined to generate a quantized output signal. Using these parallel architectures a range of weighting and offset combining schemes can be employed to achieve improvements in signal to noise ratio and to reduce the impact of clipping as compared to a single path ADC architecture.
