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.

Number Representation and Computer Arithmetic

One way to encode decimal digits using binary signals is to encode each of the digits 0-9 by means of its 4-bit binary representation. The resulting binary-coded decimal (BCD) representation is shown below:

11.2 Role of Capacitors in Transistor Amplifiers

2. As bypass capacitors. Like a cou-pling capacitor, a bypass capacitor also blocks d.c. and behaves as a short or wire (due to proper selection of capacitor size) to an a.c. signal. But it is used for a differ-ent purpose. A bypass capacitor is con-nected in parallel with a circuit component (e.g. resistor) to bypass the a.c. signal and

Because of the single supply operation, input/output coupling is via polar capacitors, namely C1, C2, and C3. C4 is a noise filter, and C5 a bypass. For lowest noise in the circuit, the amplifier biasing must also be noiseless, that is free from noise added directly or indirectly by the biasing (see Reference 1).

Bootstrap Circuitry Selection for Half Bridge Configurations

3.2 VDD Bypass Capacitor The charge to replenish the bootstrap capacitor must come from some larger bypass capacitor, usually the VDD bypass capacitor. As a rule of thumb, this bypass capacitor should be sized to be at least 10 times larger than the bootstrap capacitor so that it is not completely drained during the charging time of
