Abstract
Various embodiments relate to delta-sigma loop filters with input feedforward. A delta-sigma loop filter may include a first integrator and a quantizer having an input coupled to an output of the first integrator. The delta-sigma loop filter may further include a first summing node having an output coupled to an input of the first integrator. Further, the delta-sigma loop filter may include a feedforward path from an input of the delta-sigma loop filter to a first input of the first summing node. The delta-sigma loop filter may also include a first feedback path from an output of the quantizer to a second input of the first summing node.
