Other Parts Discussed in Thread: TINA-TI,
Tool/software: TINA-TI or Spice Models
Hi! I am currently building a simple amplifier, and the TINA-TI simulation results show the above results.
The first one shows the AC Transfer characteristic when the ideal op-amp is used.
And the second one uses the spice model of the LMH6619 op-amp.
When I switched to the real op-amp model, there was a gain increasing portion between 1MHz and 10MHz, but I don't understand what caused this.
However, a 100 Ohm resistor was connected to the output terminal, the gain increasing was disappear.
What causes these problems? Thanks! :)
