摘要：
A fully integrated current version precision continuous-time of fourth-order low pass filter with balanced structure based on current followers CF+ is presented. The characteristics of the output voltage amplitude frequency and phase-frequency response of filter have been simulated and analyzed by using the PSPICE(II). The current signal could be directly processed, the influence of the voltage tracking error on the quality factor and natural frequency could be avoided, and the even nonlinearity of the MOSFET resistors could be cancelled by this filter.
