Popis:	This paper presents a compact, reliable 1.2V low-power rail-to-rail class AB operational amplifier (OpAmp) suitable for integrated battery powered systems which require rail-to-rail input/output swing and high slew-rate while maintaining low power consumption. The OpAmp, fabricated in a standard 0.18µm CMOS technology, exhibits 86dB open loop gain and 97dB CMRR. Experimental measurements prove its correct functionality operating with 1.2V single supply, performing very competitive characteristics compared with other similar amplifiers reported in the literature. It has rail-to-rail input/output operation, 5MHz unity gain frequency and a 3.15V/µs slew-rate for a capacitive load of 100pF, with a power consumption of 99µW.
