Transistor Technologies for High Efficiency and Linearity

Differential Topology • Double the available voltage swing • Even-order harmonic suppression • Double the frequency of current injection into substrate –Reduce the potential for LO-pulling • The tail current source is removed from the standard differential pair (this is a “quasi-differential” structure) –DC current set by the biasing of input devices

Phase Locked Loop Circuits

Clock generation: B. Razavi, Design of Analog CMOS Integrated Circuits, Chap. 15, McGraw-Hill, 2001. 1. Definition. A PLL is a feedback system that includes a VCO, phase detector, and low pass filter within its loop. Its purpose is to force the VCO to replicate and track the frequency and phase at the input when in lock.

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
