摘要：

In this paper,some novel SC-adaptor circuits are presented to realize the unit element waveswitched capacitor filter using two-phase clock signals.These circuits are insensitive to the bottomplate parasitic capacitances and request only one unit-gain buffer to realize an adaptor.The effectsof top plate parasitic capacitances and switch parasitic capacitances on an adaptor are analyzed.The results show that the effects of those are small and can be reduced further by adjusting onlyone of the capacitances.These circuits are adaptable for realizing programmable filters and veryuseful to the LPC real-time speech synthesis.As an example,a 5th order unit element low-passfilter is given.The experimental results are in excellent agreement with the theory.
