Abstract: 
In this paper a novel topology of CMIA based on FDCCII is proposed. Due to benefiting from current mode signal processing, unlike the most of the previously reported IAs, the proposed FDCCII based structure doesn't need well-matched resistors or active blocks to obtain high CMRR and inherently can improve CMRR, bandwidth, power consumption and it has better frequency performances. On the other side, unlike other current mode types of this group, using fully differential structure decreases the mismatch effect in electronic blocks. Both of these advantages significantly reduced the structure size and power consumption while improving bandwidth and CMRR and makes it an excellent and an unbeatable choice for integration. In the proposed circuit, CMRR as the most important property of IA has been greatly improved by using a current subtracting stage. The CMIA has been designed using 0. 18 um CMOS Technology under ± 1 V supply voltages and the performance of the CMIA has been verified using HSPICE software in transistor level. The CMIA has achieved voltage CMRR of 227. 4 dB, voltage CMRR bandwidth of 8. 98 KHz, differential voltage gain bandwidth of 9. 08 MHz and output offset voltage of 2. 23 uV and the IA’ s power dissipation is only 348 uW.
