SpletRF attenuators. For radiofrequency (RF) work (<1000 Mhz), the individual sections must be mounted in shielded compartments to thwart capacitive coupling if lower signal levels are to be achieved at the highest frequencies. The individual sections of the switched attenuators in the previous section are mounted in shielded sections. SpletThe CMOS switched-capacitor power amplifier (SCPA) architecture was disclosed by S.M. Yoo, et al., in 2011 [1]-[2]. It enabled the design of fully-integrated radio frequency (RF) transmitters with much higher power-added efficiency (PAE) than previous approaches. Herein, new techniques are introduced that also increase SCPA linearity. Specifically, a …
