Abstract
Examples of amplifiers and n-order loop filters thereof are configured to enable fast and robust recovery from saturation, while limiting signal distortion at or near full power delivery across multiple process and temperature corners. An example n-order loop filter comprises n series-coupled resistor-capacitor (RC) integrators. In an example, each of the second RC integrator to the (n−1)RC integrator has a reset mechanism responsive to a reset signal output from a reset controller when an input signal overload condition is detected at the input. Upon detecting the overload condition, each of the third RC integrator to the (n−1)RC integrator is hard reset, the nRC integrator is not reset, and a controlled reset is performed on the second RC integrator to recover from saturation caused by the signal overload condition, while maintaining the output signal below the 1% total harmonic distortion (THD) level at or near full power delivery.
