Final answer:
Operational amplifiers with large gains are suitable for linear amplification and comparator circuits. Voltage doubling and clipping applications do not inherently require large gains to function effectively.
Step-by-step explanation:
Operational amplifiers (op-amps) with large gains are suitable for a variety of applications, but not all applications listed benefit from large gain. The most appropriate applications for large gains are:
- Linear amplification: For accurate signal amplification where the input signal is multiplied by a stable, well-defined gain factor.
- To compare: In comparator circuits where the op-amp's high gain allows for the quick determination of which of two input voltages is higher.
Applications such as voltage doubling and clipping don't inherently require large gains of an op-amp to function effectively. Voltage doublers are power circuit configurations where circuit topology, rather than op-amp gain, determines the voltage increase. Clipping circuits are designed to limit the voltage level and can be achieved with or without an op-amp.
