High gain pseudo-differential auxiliary amplifiers are used to implement the regulated cascode transistors in order to boost the output impedance of the composite input stage and the open-loop gain of the op-amp. Both input and output stages operate in class AB mode. The proposed op-amp has been simulated in a 130nm commercial CMOS process technology. It operates from a 1.2V supply and has a close to rail-to-rail differential output swing. It has 156dB DC open-loop gain and 63MHz gain-bandwidth product with a 30pF capacitive load. The op-amp has a DC open-loop gain figure of merit FOMAOLDC of 174 (MV/V) MHz pF/uW and large-signal figure of merit FOMLS of 3(V/us) pF/uW.15 p.application/pdfengThis work is licensed under a Creative Commons Attribution 4.0 License.Class-AB op-ampFully differential amplifierMiller-compensationRegulated cascodeResistive local common-mode feedbackVoltage followerinfo:eu-repo/semantics/articleAcceso abierto / Sarbide irekiainfo:eu-repo/semantics/openAccess
