A design method for MOS-compatible analogue active filters that use only integrating amplifiers and ratios of capacitors is discussed. The circuits retain most of the implementation advantages of sampled-data switched-capacitor filters, but are complementary to switched-capacitor filters in providing better and more predictable performance at high frequencies. The effects of circuit parasitics and amplifier nonidealities are discussed and experimental results are presented to illustrate the performance.
