Abstract:
An analog-to-digital converter, comprising:a first conversion block including inputs for receiving an analog input signal and an analog reference signal;a plurality of conversion blocks following said first conversion block each comprising:means for receiving said analog input signal and said analog reference signal, and at least one analog integrator input and at least one digital decimator input from a previous conversion block,a D/A converter having at least one distinct analog output level and an analog input of said analog reference signal, and s digital input of said at least one digital decimator input,at least one integrator,a quantizer that computes at least one bit as an output,means for combining the output of said quantizer with said at least one digital decimator input, andmeans for providing an analog output signal output, at least one analog integrator output, and at least one digital decimator output to a following conversion block; andmeans for generating a result from said at least one digital decimator output at the last of said conversion blocks.
