Abstract
A continuous time delta-sigma modulator is provided that includes an integrator stage including a plurality of integrators; a quantizer to receive an input signal from the integrator stage and output a quantizer signal; a global feedback path providing feedback from the quantizer to the integrator stage; a local feedback path connecting the quantizer and a preceding integrator of the integrator stage configured to compensate for delay attributed to the global feedback path; and a delay compensation circuit. The delay compensation circuit is configured to calculate a delay value based on sources of additional delay within a local feedback loop, and to supply the additional delay value to the quantizer to compensate for delay within the local feedback loop.
