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

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.

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.

Open circuit voltage = 1.6 Volts 1.6 Volts – 0.1 Volts = 1.5 Volts (expected closed circuit voltage) In general, internal resistance will rise during discharge due to the active materials within the battery being used. However, the rate of change during discharge is not consistent. Battery chemistry, depth of discharge, drain rate and

The choice of flip-flop type can affect the complexity of the combinational logic in the resulting sequential circuit. Of three common types, the most versatile is the JK, since it can be easily converted into the other two.
