摘要： A circuit may include a detector, an approximator, a look-up table, a scaler, and an integrator. The detector may generate a first difference signal and a second different signal based on an input and an output. The approximator may generate, using a one's complement operation, an index based on approximated modulus values of the first difference signal and the second difference signal. The look-up table may select one of a plurality of scaling factors based upon the index. The scaler may adjust the first difference signal and the second difference signal based on the selected scaling factor. The integrator may generate the output based on the adjusted first difference signal and the adjusted second difference signal.
