In this chapter, the potential of the circuit topologies proposed in the work is validated by experimental evaluation of the prototypes. The test configurations and measurements are thoroughly detailed. A final comparison with the state of the art is provided. The description of the designed and fabricated test printed circuit board is described in Sect. 5.1. The practical realization and the corresponding experimental evaluation of the voltage-combiner-biased OTA are described in Sect. 5.2. The practical realization and the corresponding experimental evaluation of the voltage-combiner-biased OTA improved with current starving are described in Sect. 5.3. This chapter positions the developed work within recently published literature, emphasizing the clear contribution in terms of energy efficiency, showing performance beyond the state of the art of single-stage amplifiers, particularly in the context of dynamic amplification.
