Power Amplifiers for Communications

Peak E ciency Power Added E ciency (PAE) is a popular metric. P out is the output power, P in is the input power, and P dc is the DC power consumption of the PA For high power gain systems (G p), the e ciency approaches the drain drain e ciency ( d), or for a BJT, the \collector" e ciency, or simply the e ciency of the last stage

Lecture 12: Noise in Communication Systems

The noise of the first stage is the most important. Thus, every communication system employs a low noise amplifier (LNA) at the front to relax the noise requirements A typical LNA might have a G = 20dB of gain and a noise figure NF < 1.5dB. …

A fifth-order Chebyshev filter with 0.2dB ripple is down about 80dB at the IF frequency. But the Q for such a filter is Q = 103MHz 1MHz = 103 Such a filter requires components with Q > 103! A. M.

Nonlinear System Theory

phase-plane analysis describes nonlinear phenomena such as limit cycles and multiple equilibria of second-order systems in an efficient manner. The theory of differential equations has led to a highly developed stability theory for some classes of nonlinear systems. (Though, of course, an engineer cannot live by stability alone.) Functional

Band-bending - Iowa State University

In the p-n junction and BJT, we saw that the semiconductor band edges were bent in the depletion layers. We used the depletion approximation and Poisson’s equation to relate the band-bending (barrier height) to the electric field to the depletion layer width. In the case of depletion, our treatment is reasonably accurate. However, we

Bootstrap Circuitry Selection for Half Bridge Configurations

A bootstrap circuit is used in half-bridge configurations to supply bias to the high-side FET. Figure 1 shows the charging path of a bootstrap circuit in a simplified half-bridge configuration using UCC27710, TI's 620V half-bridge driver with interlock. When the low-side FET is on (high-side FET is off), the HS pin and the
