“…A current-mode type of dual VOA is referred to as a current operational amplifier (COA) (Arbel and Goldminz 1992;Abou-Allam and El-Masry 1997;Cheng and Wang 1997;Kilinc¸and Ç am 2003;Uygur and Kuntman 2004). Current operational amplifiers have been derived to obtain current-mode operation together with current-mode circuits and higher bandwidth.…”

In this paper, improved CMRR, high gain CMOS current-mode operational amplifier (COA) is presented. A new class AB input stage is used in order to obtain very low input resistance. The proposed COA is operated under ±1.5 V voltage supplies and designed with 0.35-μm CMOS process. Results of simulation indicate a 107 dB DC gain, 123 Ω input resistance, common mode rejection ratio exceeding 110dB and a gain-bandwidth product at about 100 MHz.

Design guidelines for CMOS current amplifiers with a high-drive capability are discussed in detail, paying special attention to the implementation of output stages with improved linearity performance. As a design example, two different current amplifiers were realized in a 1.2-m process and experimentally tested. Both circuits used a 5-V power supply and dissipated 5.5 and 4 mW, respectively. The open-loop gain was found to be 90 and 100 dB and the gain-bandwidth product was 8 and 10 MHz. The two amplifiers provide bipolar output currents as high as 15 and 7 mA, with a maximum total harmonic distortion of around 54 dB, using a quiescent current in the output branches of only 200 A.Index Terms-CMOS analog integrated circuits, current mode, integrated circuit design, operational amplifiers, power amplifiers.
