Abstract: The error functions of CCII-based integrators are analysed. On this basis, the fully integrated CCII-based continuous-time bandpass filters consisted of double integrator loops are studied, and the relationship between the centre frequency p and Qp and the magnitude E and the phase E of the error function is also discussed. The effects of nonideal CCII are considered in detail. The conclusions obtained may provide foundation and improvement for the design of CCII-based MOSFET continuous-time higher order filters. -
