dc.description.abstract | This brief presents the design of a single-stage amplifier with enhanced gain and speed, without the need for using any cascode devices, positive feedback, or feed forward technique. Instead, two voltage-combiners replace the traditional tail current source, commonly employed to bias the differential pair. The resultant topology shows both additional dc gain and a gain bandwidth product enhancement. Simulation results of a properly optimized circuit, using AIDA-C, a state-of-the-art multi-objective multi-constraint IC sizing and optimization tool, demonstrate that a dc gain above 47 dB and a figure-of-merit better than 960 MHz*pF/mA, in corner conditions, can be achieved with this topology, in the UMC 130-nm technology. The circuit was fabricated and experimentally measured, showing an energy-efficiency figure-of-merit of 1023.6 MHz*pF/mA. | pt_PT |
