摘要：
In this paper, the characteristics of the basic current mirror and the continuous-time current-mode current mirror integrator are analyzed. Using the two unlossy loop integrators and the basic current mirrors, the biquad circuit block is implemented The signal flow graph (SFG) and the improved leap frog (ILF) structure are simple to implement the six-order band pass filters. Exploring PSPICE9.1 simulation in 0. 18 mu m CMOS technology, Transistor lever circuit is carried out and results show that the proposed circuit is feasible. The design method of biquad block circuits is apt to realize the high-order band-pass filter and elliptic function filter..
