The circuit utilizes OPA2662's internal two OTAs to constitute a common-emitter amplifier, that is, input end is added 150Ω current limiting resistor and 50Ω termination resistor, and the signal is amplifed to pass CR3425 and drive CRT monitor. At the input end, , tR = 0.7 ns , tF = 0.7 ns ; , tR = 2.4ns , tF = 2.15ns.
