What I'm doing:
I'm applying voltage pulses to thin films and measuring the resulting current transient, then using these transients to extract the hole mobility.
When the films are very thin, the transient cannot be observed as a result of a capacitive response. The paper I am reading from describes a circuit used to "clean up" up the transient by removing this capacitive response:
In order to overcome this problem, we used a simple bridge circuit ... where a differential ampliﬁer is used to subtract the capacitive response of the circuit recovering the ‘‘pure’’ SCLC transient
The problem, as my background is in physics, is I have no idea how I'd even start to use this circuit (connecting with the oscilloscope, what values for the components etc).
What I'm asking:
Does this type of bridge circuit have a specific name so I'm able to learn about it and find out how I'd be able to use it? I'm basically just asking for a starting point that will allow me to read into how this circuit would work.
