Abstract
This chapter presents the application of silicon nanowire technology on another analog domain: RF receivers. RF receivers contain two important functional blocks. The first block is the down-converter unit. This block consists of a low noise amplifier, a mixer, and an oscillator. It is mainly used to translate a high frequency signal to a lower frequency signal for baseband processing. The second block is the Variable Gain Amplifier (VGA). Because the signal strength largely depends on the distance between the receiver and transmitter, the VGA regulates the signal strength before the re-conditioned signal arrives at the input of the baseband processor. The design approach and the circuits incorporating SNTs are fully examined in this chapter to design and analyze both of these units. The layout of each SNT includes a re-engineered source structure as well as extra gate and source contacts to minimize high terminal resistances as they deteriorate the overall noise factor of the RF receiver and make the input impedance matching difficult.
