Square Output, Duty Cycle: 46.8%
Unfortunately, without knowing the specific details of the first circuit, it is not possible to determine the maximum operating frequency or which op-amp parameter has a significant effect on it. The information provided only gives details about the output signals (square and triangle) and their amplitudes, frequency, and duty cycle. The maximum operating frequency of a circuit depends on various factors such as the design, components used, and their specifications. Additionally, different op-amp parameters can have an impact on the circuit's performance, including bandwidth, gain-bandwidth product, slew rate, and input/output capacitance.
To determine the maximum operating frequency of the first circuit, we need more information about the circuit itself. The information provided in your question does not include the circuit's specifics, such as the configuration of the op-amp, the type of filter used, or other relevant details.
However, in general, the op-amp parameters that can significantly affect the maximum frequency are the gain-bandwidth product (GBW) and the slew rate.
The gain-bandwidth product (GBW) is the product of the op-amp's open-loop gain and the bandwidth at which that gain is measured. It represents the frequency at which the open-loop gain drops to 1 (0 dB). A higher GBW product indicates better response characteristics at higher frequencies. So, an op-amp with a higher GBW product will generally have a higher maximum operating frequency.
The slew rate is the maximum rate at which the op-amp output can change. It is usually expressed in volts per microsecond (V/µs). The slew rate represents the op-amp's ability to follow rapid changes in the input signal. A higher slew rate allows the op-amp to handle faster input signals, resulting in a higher maximum operating frequency.
Again, it's essential to have more information about the specific circuit being considered to accurately determine the maximum operating frequency and the op-amp parameter that has a significant effect on it.
