1 or Op Amps for short
2 Objective of Lecture Describe how an ideal operational amplifier (op amp) behaves. Chapter 14.1 Electrical Engineering: Principles and Applications Chapter Fundamentals of Electric Circuits Define voltage gain, current gain, transresistance gain, and transconductance gain. Chapter Electrical Engineering: Principles and Applications Explain the operation of an ideal op amp in a voltage comparator and inverting amplifier circuit. Show the effect of using a real op amp.
3 Op Amps Applications Audio amplifiers Speakers and microphone circuits in cell phones, computers, mpg players, boom boxes, etc. Instrumentation amplifiers Biomedical systems including heart monitors and oxygen sensors. Power amplifiers Analog computers Combination of integrators, differentiators, summing amplifiers, and multipliers
4 Symbols for Ideal and Real Op Amps OpAmp ua741 LM111 LM324
5 Terminals on an Op Amp Non-inverting Input terminal Positive power supply (Positive rail) Output terminal Inverting input terminal Negative power supply (Negative rail)
6 Op Amp Equivalent Circuit v 2 v d = v 2 v 1 A is the open-loop voltage gain v 1 Voltage controlled voltage source
7 Typical Op Amp Parameters Parameter Variable Typical Ranges Open-Loop Voltage Gain Ideal Values A 10 5 to 10 8 Input Resistance Output Resistance Ri 10 5 to Ω Ω Ro 10 to 100 Ω 0 Ω Supply Voltage Vcc/V + -Vcc/V - 5 to 30 V -30V to 0V N/A N/A
8 How to Find These Values Component Datasheets Many manufacturers have made these freely available on the internet Example: LM 324 Operational Amplifier

10 db Decibels Since P = V 2 /R 10 log (P/P ref ) or 20 log (V/V ref ) In this case: 20 log (V o /V in ) = 20 log (A) = 100 A = 10 5 = 100,000
11
12 Large Signal Voltage Gain = A Typical A = 100 V/mV = 100V/0.001V = 100,000 Minimum A = 25 V/mV = 25 V/0.001V = 25,000
13 Caution A is Frequency Dependent
14 Open Circuit Output Voltage v o = A v d Ideal Op Amp v o = (v d )
15 Open Circuit Output Voltage Real Op Amp Voltage Range Output Voltage Positive Saturation A v d > V + v o ~ V + Linear Region V - < A v d < V + v o = A v d Negative A v d < V - v o ~ V - Saturation The voltage produced by the dependent voltage source inside the op amp is limited by the voltage applied to the positive and negative rails.
16 Voltage Transfer Characteristic Range where we operate the op amp as an amplifier. v d
17 Ideal Op Amp Because Ri is equal to Ω, the voltage across Ri is 0V. v 2 i 2 = 0 v 1 = v 2 v d = 0 V v 1 i 1 = 0
18 Almost Ideal Op Amp Ri = Ω Therefore, i 1 = i 2 = 0A Ro = 0 Ω Usually, v d = 0V so v 1 = v 2 The op amp forces the voltage at the inverting input terminal to be equal to the voltage at the noninverting input terminal if there is some component connecting the output terminal to the inverting input terminal. Rarely is the op amp limited to V - < v o < V +. The output voltage is allowed to be as positive or as negative as needed to force v d = 0V.
19 Example #1: Voltage Comparator i s = 0 i 1 = 0 i 2 = 0 Note that the inverting input and non-inverting input terminals have rotated in this schematic.
20 Example #1 (con t) The internal circuitry in the op amp tries to force the voltage at the inverting input to be equal to the noninverting input. As we will see shortly, a number of op amp circuits have a resistor between the output terminal and the inverting input terminals to allow the output voltage to influence the value of the voltage at the inverting input terminal.
21 Example #1: Voltage Comparator i s = 0 i 1 = 0 i 2 = 0 When Vs is equal to 0V, Vo = 0V. When Vs is smaller than 0V, Vo = V +. When Vs is larger than 0V, Vo = V -.
22 Electronic Response Given how an op amp functions, what do you expect Vo to be if v2 = 5V when: 1. Vs = 0V? 2. Vs = 5V? 3. Vs = 6V?
23 Example #2: Closed Loop Gain i f i s i 1 = 0 v 1 i 2 = 0 v 2
24 Example #2 (con t) i f i s i 1 i o i 2 For an almost ideal op amp, Ri = Ω and Ro = 0 Ω. The output voltage will never reach V + or V -.
25 Example #2 (con t) Virtual ground i f i s i 1 i i 2 The op amp outputs a voltage Vo such that V1 = V2.
26 Example #2 (con t) i s i 1 i f i i 2
27 Example #2: Closed Loop Gain This circuit is known as an inverting amplifier / / / 0 R R A R R V v i i i i R v R i V V v f V f s o f s f f o s S = = = = = = = C A B
28 Types of Gain i f i s i 1 i o i i 2
29 Types of Closed Loop Gain Gain Variable Name Equation Units Voltage Gain A V v o /v s None or V/V Current Gain A I i o /i s None or A/A Transresistance Gain A R v o /i s V/A or Ω Transconductance Gain A G i o /v s A/V or Ω 1
30 Example #3: Closed Loop Gain with Real Op Amp i f i s i 1 v 1 i i 2 v 2
31 Example #3 (con t) i s = i 1 + i f i = i f - i 1 = i 2 v d = v 2 v 1 = Ri (- i 1 ) = Ri (i 2 ) V o = Av d - Ro(- i) V s = R1(i s ) v d V s = R1(i s ) + Rf(i f ) + V o V o /V s = (-R f /R1){Aβ/[1 +Aβ]}, where β = R1/(R1+R f )
32 Summary The output of an ideal op amp is a voltage from a dependent voltage source that attempts to force the voltage at the inverting input terminal to equal the voltage at the non-inverting input terminal. Almost ideal op amp: Output voltage limited to the range between V + and V -. Ideal op amp is assumed to have Ri = Ω and Ro = 0 Ω. Almost ideal op amp: v d = 0 V and the current flowing into the output terminal of the op amp is as much as required to force v 1 = v 2 when V + < v o < V -. Operation of an op amp was used in the analysis of voltage comparator and inverting amplifier circuits. Effect of Ri < Ω and Ro > 0 Ω was shown.
