High Voltage Design Considerations
IN Chapter 3 it is demonstrated, by high-level modeling, that the SOPA amplifier does not benefit in terms of distortion and noise from the low supply voltages originating from nanometer CMOS technologies. It was also proved that these low voltage issues can be circumvented by operating the critical path of the SOPA line driver, the power delivering output stage, at higher voltages. In this chapter, the influence of low supply voltages on the SOPA line driver design will be further elaborated in terms of efficiency and reliability and possible solutions will be discussed.
