BEC ANNEX 4

Operational Amplifier Characteristics

- high gain - direct coupled - provide gain - 200,000+

I.C. Chip (Integrated Circuit Chip)

- made of silicone - smaller/ less power - less expensive Digital IC for computer Linear IC for analog

Value of forward bias 8====D

0.6

In a Data Flip Flop, PR input produces a ______, CLR produces a _____, when activated.

1, 0

Inverted input has a _________ degree phase shift

180

There are __ blocks in dc to dc converters

4

Not gate

A logic gate that takes in 1 input & outputs the opposite

RS flip flop

Activated one at a time, R produces 1, S produces 0

And Gate

Ass and kitties

Or Gate

Ass or kitties

Wave shaping

Cleans up data signals

Control Circuit

Determines is the switch driver is on or off

3 Functional Blocks in an Op Amp

Differential Amplifier, Voltage Amplifier, Output Amplifier

Piezoelectric effect (mechanical)

Electrical current produced by applying pressure to crystals determined by the size and cut

Oscillator

Generates a given waveform at a CONSTANT AMPLITUDE, and SPECIFIED FREQUENCY

Power Switch

Increases current and voltage

JK Flip FLop

Is able to function as any other flip flop

Output Amplifier

Low impedance matching, max transfer of power

Two types of oscillators

Mechanical and electrical

Binary to Decimal

Multiply by powers of 2 beginning with the rightmost digit, crosscut zeros, then add the remaining numbers

Voltage Amplifier

Provides GAINS

Differential amplifier

Provides the input, high input impedance

Filter and Clipper

Regulates output signal

Switch Driver

Sets frequency

frequency determining network

Sets the frequency

PR input and CLR input cannot be active at the same time (true/false)

True

Reference input must be higher than the output for the switch driver to turn on (true/ false)

True

Amplifier Switching Network

amplifies signal through transistors

Decimal to Binary

divide by 2 and keep remainder

Closed loop

feedback ;)

3 functional areas of oscillator

frequency determining network, amplifier switching network, feedback network

Xor gate

gay marriage not allowed

Value of reversed bias

given value of zener diode

Regenerative feedback is also known as _____________

hysteresis

Degenerative Feedback

inverted feedback

Open loop

no feedback

RC Feedback (electrical) is also known as

phase shift

Feedback network

purpose is to prevent signal dampening

Two types of feedback

regenerative, degenerative
