SUMMARY

The discussion centers on the relationship between gain-bandwidth product and slew rate in operational amplifiers (op-amps). A high gain-bandwidth product does not inherently guarantee a high slew rate, as it is contingent on the maximum output voltage required. The phase sensitive detector operates at a reference frequency of 100kHz, necessitating a calculated maximum RMS voltage for input signals based on the specified slew rate of 1V/μs. The maximum slew rate for an op-amp outputting a voltage of V0sin(ωt) is directly influenced by these parameters.

PREREQUISITES
  • Understanding of operational amplifier (op-amp) fundamentals
  • Knowledge of gain-bandwidth product concepts
  • Familiarity with slew rate calculations
  • Basic principles of phase sensitive detection
NEXT STEPS
  • Research the relationship between gain-bandwidth product and slew rate in op-amps
  • Learn how to calculate maximum RMS voltage for input signals based on slew rate
  • Explore the specifications and performance characteristics of various op-amps
  • Study phase sensitive detector design and its frequency response
USEFUL FOR

Electrical engineers, circuit designers, and students studying analog electronics who are interested in optimizing op-amp performance and understanding signal processing techniques.

Question
The op-amp selected for the unity gain inverter, has a gain-bandwidth product, and maximum slew rate at its output of 1V/μs[/b]
(i) Justify the statement that a high gain-bandwidth product necessarily leads to a high slew rate
(ii) The phase sensitive detector is expected to operate with a reference frequency set at 100kHz. Based on the slew rate given, determine a maximum rms voltage for input signals and explain your reasoning
My problem
Don't really know where can I get the gain-bandwidth product. I feel there's no need to present my attempt at a solution, because it's not the type of question that will require derivation or anything.
Thanks for your help (in advance)
 
Physics news on Phys.org
An op amp outputs a voltage V0sin(ωt). What's the maximum slew rate?

(I hate to muddy the water, but actually the statement is not necessarily correct. Hint: it depends on the max output voltage required).
 
Sorry, stupid question. Just needed to differentiation once.
