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
