Abstract :
The continuing demand for higher bandwidth and lower power dissipation requires extremely efficient analog design techniques. An overview of these techniques is given for the design of input stages, output stages, frequency compensation and overall design of amplifiers. Also, operation down to the lowest supply voltage, which equals one gate-source voltage and one saturation voltage, is addressed.
