Is there a current feedback operational amplifier such as the AD844 that could be included ? |

Figure 28 of the AD844 datasheet provides an equivalent schematic. You can implement this easily as something like this: You can copy and paste this into your own circuit. For example, let's try to replicate Figure 29, the inverting amplifier: Run this one and check out the frequency domain simulation. This confirms the 3rd-to-last entry in Table 3 of the datasheet, showing a gain of -10 and a bandwidth of 33 MHz. |

Appreciate the answer, however since the circuits I need to simulate require many of these i need it as a building block. It appears to me that this is not possible with circuitlab. Am I correct there? |

Correct. Copy & paste is the easiest way forward. You could also probably simplify the internal model if that helped. For example, the low-pass action of Rt and Ct could get bundled into BUF2, switching out CCCS1 for a CCVS. |
