Common-emitter amplifier circuit composed of double broadband transconductance operational amplifier OPA2662
The circuit uses the OPA2662 internal dual OTA connected in parallel to constitute a common-emitter amplifier. The input end is connected 100Ω current limiting resistor in parallel, the input signal is input by 2 feet and 7 feet. 14 feet and 10 feet are connected the collector, 15 feet and 11 feet are connected to constitute the emitter, BFQ262 and 430Ω resistor form collector load, and the signal will be output after beng amplified, and the input and output waveforma are shown in Fig.
