His ill-advised first try involved directly coupling two switches ... from a second pair of switches he wired up some resistor-capacitor networks on a breadboard and got the connecting to ...

An undesired voltage spike resulting from this capacitive coupling is commonly referred to as crosstalk. The presence of another nearby line will increase the total capacitance of the isolated line.

This paper describes how we can make small modification on a capacitive cross-coupling technique to improve noise figure or flatness of very wide range LNA. Section II discusses noise cancellation ...
