GaAs switched capacitor voltage converter

GaAs technology is becoming a mainstream technology for consumer applications. GaAs ICs can be found in satellite TV, cable TV and fiber optic receivers. In wireless products, GaAs receiver ICs as well as power amplifier MMICs are being used in the millions. In power amplifiers, the low ON resistance of the MESFET combined with the high F _τ allows for highly efficient RF power amplification. In DC-DC power converter applications, high efficiency and high switching speeds are of critical importance. For these applications, GaAs MESFET technology has shown major advantages. The author predicts that GaAs MESFET technology will make inroads into hand held applications such as cordless phones, cellular phones and pagers
