The Wideband Amplifier Circuit is shown below. The picture (a) and picture (b) have not only the differences on the input signal's symbol, but also the differences on the input impedance |Ze|. Its main technical data is listed below. Amplifier TypeOut-phase input port (picture a) In-phase input port (picture b) Low frequency closed-loop amplification factor |Vo'| 100 100 3dB bandwidth b >20MHz >20MHz Supply Voltage Up=-Un 8V 8V Input impedance |Ze| 111Ω >100kΩ Load Capacitance Cl <=22pF <=22pF
