N2 - In this paper, a CMOS current-mode operational amplifier (COA) based on a novel, class A input stage and a folded-cascode output stage is presented. The amplifier provides a 95 dB DC gain and a gain-bandwidth product exceeding 200 MHz. The COA is operated under ±1.5 V voltage supplies and designed with 0.35-μm CMOS process. Additionally, COA-based band-pass filter is realized. In a multiple feedback band-pass filter topology, COA can be used instead of voltage amplifier to enhance the bandwidth of operation. The center frequency of the filter is 10 MHz.
