It is now important to develop the major building blocks of modern RF circuits and this chapter will cover amplifier design. The amplifier is usually required to provide low noise gain with low distortion at both small and large signal levels. It should also be stable, i.e. not generate unwanted spurious signals, and the performance should remain constant with time. A further requirement is that the amplifier should provide good reverse isolation to prevent, for example, LO breakthrough f……
