Present day data processing technology requires very high speed signal processing and data conversion rates. One such application which requires high speed is switched capacitor circuits used in Sigma-Delta modulators. A major active component of switched capacitor circuits is the monolithic operational amplifier(opamp). Because of the relatively poor speed performance...
Present day data processing technology requires very high speed signal processing
and data conversion rates. Traditionally, these circuits have been implemented in silicon
MOS technology, whose high speed performance is limited, due to inherent material properties.
Though relatively immature compared to silicon technology, GaAs integrated circuit
technology appears to be...
