NOTE: This interface network creates a capacitive, constant current source from a network analyzer and properly terminates the network analyzer
at high frequencies.

, above the pole frequency, providing a controllable AC current source. This circuit
also properly terminates the network analyzer with 50
at high frequencies. The second requirement for this
current source is to provide the desired output impedance, emulating the output impedance of a photodiode or
other current source. The output impedance of this circuit is given by

giving the appearance of a capacitive source at higher
frequency.
Capacitor values should be chosen to satisfy two requirements. First, C2 should represent the anticipated
capacitance of the true source. C1 should then be chosen such that the corner frequency of the
transconductance network is much less than the transimpedance bandwidth of the circuit. Choosing this corner
frequency properly leads to more accurate measurements of the transimpedance bandwidth. If the interface
circuit’s corner frequency is too close to the bandwidth of the circuit, determining the power level in the flatband
is difficult. A decade or more of flat bandwidth provides a good basis for determining the proper transimpedance
bandwidth.
