Abstract
An amplifier is disclosed including multiple integrator stages. The amplifier includes a low-frequency path from a signal input to a signal output and relatively higher-frequency bypass paths around the first integrator stage. The paths converge at a summing node. To prevent instability when the integrators are saturated by large signals, the circuit includes a saturation detector which disables the relatively low-frequency paths during such saturation conditions.
