ABSTRACT:
A sigma delta analog-to-digital converter (100) comprising a second or third order integrator block (105) featuring a feed-forward connection path between the input of the integrator block and an input of at least one of the plurality of integrators (130 or 150). A comparator (180) coupled to the output of the integrator block (105) generates as output a digital value representing a difference between the integrator output signal with respect to a threshold, or in a differential mode implementation, between component signals of a differential signal output by the integrator block (105). A digital sampling element (190) coupled to the output of the comparator (180) samples the output of the comparator (180) in response to a sampling clock signal at a predetermined sampling frequency to generate as output digital signal comprising samples of the digital values output by the comparator (180).
