Flashcards in ITEC 320 Final Deck (14):
1

Integrated circuits

An integrated circuit, or group of circuits, formed on a very small chip of material called a substrate.

2

Chip

Another name for an integrated circuit (IC)

3

Operational amplifier

A high-gain, direct-coupled amplifier that uses feedback to provide well-stabilized voltage gain. Also called op amp. Most often op-amps are ICs

4

Op-amps have high/low input impedances and high/low output impedances

High input impedance and low output impedance

5

Is the gain of an op-amp high or low

High

6

An 1C is formed on a

Chip of silicon

7

Operational amplifiers have very high input impedance's and

Very low output impedance's and high gains

8

Generally, op-amp circuits use negative feedback to

Control the gain and stabilize the amplifier

9

IC's do not tolerate

Excess supply voltages

10

The voltage gain of an op-amp is

R2/R1

11

Op-amp circuits that exhibit phase reversal are

Inverting amplifiers

12

The output from an astable multivibrator is

Square-wave oscillations at controlled frequencies

13

In a free-running multivibrator circuit, the circuit starts oscillating when

Power is applied and power is removed

14

This is generally used to power op-amp circuits

Bipolar regulated power supply
