英文摘要：

A translinear MDDCCII circuit constructed by bipolar transistors is proposed. The principle is analyzed in detail and experiment on the circuit is made. In the frequency range of 0～1.5 MHz, the proposed circuit meets port characteristic of ideal MDDCCII with small track er- rors. The voltage track error is equal to 0. 01, non-inverting and inverting current track error equal 0.01, and 0.02, respectively. As an application, second order low-pass and high-pass filters are constructed by the MDDCCII, and hardware experiment on the filters are taken.
