ABSTRACT:
An oversampling analog-to-digital modulator includes an analog loop filter which has a first integrator stage which operates as a continuous time integrator. the second, third, and fourth integrator stages are discrete time or sampling integrators. The continuous time first integrator provides the required thermal noise characteristics of the loop filter while the discrete time integrator stages provide loop stability and transfer characteristics which are advantageous to the overall operation of the analog-to-digital modulator.
