It uses a simple auxiliary circuit that enhances the op-amp's gain-bandwidth product and helps to drive a wide range of capacitive and resistive loads with high static and dynamic current efficiency. Simple Miller compensation is used to obtain stability over a wide range of loading conditions. The op-amp's simulation and experimental results in strong inversion with 15uA bias current and in sub-threshold with 250nA bias current are shown. Its performance is measured in terms of dynamic and static current efficiency figures of merit FOMCEDyn and FOMCEStat: and using the conventional small-signal figure of merit FOMSS: Experimental results of op-amps fabricated in a 130nm CMOS technology are shown that validate the proposed approach.15 p.application/pdfengCreative Commons Attribution 4.0Analog integrated circuitClass-AB amplierMiller compensationVoltage followerWide range loadinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
