It employs local common-mode feedback using two matched tuneable active resistors, allowing to adapt the amplifier to different process variations and loads. Measurement results from a test chip prototype fabricated in a 0.5 μm CMOS process validate the proposal.2 p.application/pdfeng© The Institution of Engineering and TechnologySemiconductor integrated circuit designLayoutModelling and testingCMOS integrated circuitsAmplifiersAnalogue circuit designModelling and testingSuper class AB RFC OTA with adaptive local common-mode feedbackinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccessAcceso abierto / Sarbide irekia
