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

LECTURE 130 – VOLTAGE-CONTROLLED OSCILLATORS

Introduction to Voltage-Controlled Oscillators What is an oscillator? An oscillator is a circuit capable of maintaining electric oscillations. An oscillator is a periodic function, i.e. f(x) = f(x+nk) for all x and for all integers, n, and k is a constant. All oscillators use positive feedback of one form or another. Classification of oscillators:

oscillators carry out complex motion, we can find a coordinate frame in which each oscillator oscillates with a very well defined frequency. A solid is a good example of a system that can be described in terms of coupled oscillations.

Matthew Schwartz Lecture 3: Coupled oscillators

Coupled oscillators 1 Two masses To get to waves from oscillators, we have to start coupling them together. In the limit of a large number of coupled oscillators, we will find solutions while look like waves. Certain features of waves, such as resonance and normal modes, can be understood with a finite number of oscilla-tors.

Oscillator Circuits

Tuned Oscillators use a parallel LC resonant circuit (LC tank) to provide the oscillations. There are two common types: • Colpitts – The resonant circuit is an inductor and two capacitors. •Hartley– The resonant circuit is a tapped inductor or two inductors and one capacitor.

This is because all the oscillators that require external passive components (external resonator, load capacitors, etc.) covered by this document are of the previously mentioned type and topology. The harmonic oscillator family can be divided into two main sub-families: negative-resistance oscillators positive-feedback oscillators.
