equations. The syntax is: gp_circle(S, gain, # points on circle) where S is the S-parameter matrix. Let’s illustrate. In the example below, a table is used to display frequency, maximum stable gain (MSG), the stability factor, k, and the magnitude of delta. The gain circles are at MSG (MaxGain1 in this case), and 1 and 2 dB below MSG.

Audio Amplifier Circuit - UC Santa Barbara

Week #1: Audio amplifier Week #2: Microphone circuit The audio amplifier project is more difficult and time-consuming than the microphone pre-amp, so part of week #2 may be used to finish the audio amp. All breadboarding and testing can and should be done in lab. Soldering and hardwiring can and should be done outside lab.

Quality factor, Q

When a resonant circuit is connected to the outside world, its total losses (let’s call them RP or GP) are combined with the source and load resistances, RS and RL. For example, Here is a parallel resonant circuit (C,L and RP)connected to the outside. The total Q of this circuit is called the loaded Q or QL and is given by

The Delay-Locked Loop - University of California, Los Angeles

Delay-locked loops (DLLs) can be considered as feedback circuits that phase lock an output to an input without the use of an oscillator. In some applications, DLLs are neces-sary or preferable over phase-locked loops (PLLs), with their advantages including lower sensitivity to supply noise and lower phase noise. This

MT-086: Fundamentals of Phase Locked Loops (PLLs)

A phase-locked loop is a feedback system combining a voltage controlled oscillator (VCO) and a ... counter element to bring the very high input frequency down to a range at which standard CMOS will operate. This counter, called a prescaler, is shown in Figure 3B.
