Abstract
A delta-sigma modulator includes two integrators. One of the two integrators is lossy. The lossy integrator may be a continuous-time integrator, or a discrete-time integrator. Use of the lossy integrator maintains stability of the delta-sigma converter over a relatively wide range of input signals.
