**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. 


**The problem:**

When the films are very thin, the transient cannot be observed as a result of a capacitive response. [The paper I am reading from][1] 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.

**What I've tried:**

 - General googling on bridge circuits, but it turns out it's a massive topic and I wasn't able to find anything specific to subtracting capacitive responses.
 - In the paper I linked, it says the circuit is "described by Scott et al [21]". I have [found this paper][3], however it is locked behind a paywall.
