Study Notes
Comparison of Real and Ideal Operational Amplifiers
- Input Impedance:
- Ideal Op-Amp: Infinite
- Real Op-Amp: Finite (typically 1MΩ or more)
- Output Impedance:
- Ideal Op-Amp: Zero
- Real Op-Amp: Not Zero (typically a few ohms to a few hundred ohms)
- Open Loop Gain:
- Ideal Op-Amp: Infinite
- Real Op-Amp: Finite (typically 10^5 to 10^6)
- Bandwidth:
- Ideal Op-Amp: Infinite
- Real Op-Amp: Finite (decreases as frequency increases)
- Input Offset Voltage:
- Ideal Op-Amp: Zero
- Real Op-Amp: Not Zero (a small DC voltage is required at the input to force the output voltage to zero)
- Input Bias Current:
- Ideal Op-Amp: Zero
- Real Op-Amp: Not Zero (small DC currents flow into the input terminals)
- CMRR (Common Mode Rejection Ratio)
- Ideal Op-Amp: Infinite
- Real Op-Amp: Finite (common mode gain is not zero)
- Slew Rate:
- Ideal Op-Amp: Infinite
- Real Op-Amp: Finite (the rate at which the output voltage can change is limited)
- Output Voltage:
- Ideal Op-Amp: Can reach any value
- Real Op-Amp: Limited by supply voltages
- Characteristics:
- Ideal Op-Amp: Linear, does not change with temperature or time
- Real Op-Amp: Can deviate from linearity; can change with temperature, time, and supply voltage variations
- Noise:
- Ideal Op-Amp: Zero
- Real Op-Amp: Not Zero (the amplifier adds noise to the signal)
- Applications:
- Ideal Op-Amp: Circuit modeling and analysis
- Real Op-Amp: Designing real electronic circuits
- Cost:
- Ideal Op-Amp: Free
- Real Op-Amp: Has a cost
- Power Supply:
- Ideal Op-Amp: No power supply needed
- Real Op-Amp: Requires DC power supply (often dual, e.g., ±15V)
- Dimensions:
- Ideal Op-Amp: Does not exist physically
- Real Op-Amp: Exists physically in an integrated package
- Power Dissipation:
- Ideal Op-Amp: None
- Real Op-Amp: Dissipates power (must be considered in thermal design)
- Temperature Effects:
- Ideal Op-Amp: Insensitive
- Real Op-Amp: Sensitive (parameters can drift with temperature)
- Reliability:
- Ideal Op-Amp: Perfectly reliable
- Real Op-Amp: Can fail
- Tolerances:
- Ideal Op-Amp: No tolerances (parameters are exactly as specified)
- Real Op-Amp: Parameters have tolerances (e.g., open loop gain can vary by ±20%)
