Voltage amplifier pdf Quantum Noise Limits in Amplifiers 6. Voltage gain A v is about the same as a stand-along CE Amplifier. 2. The voltage source sees the high input impedance of the op-amp, so most of the voltage is dropped across this impedance rather than across the internal resistance of the source (Rs). However, they are much less linear. Based on its output Depending upon the parameter that is amplified at the output, there are voltage and power amplifiers. Figure 7. . For ampliļ¬ers that employ shunt summing at the input (also called current summing), the input variable must be a current. Supply voltage and range 3.
