4.2.2 Measuring loop gain

The results of measuring the loop characteristics (loop gain characteristic) of a negative feedback loop are

phase margin and gain margin, which are indicators of negative feedback loop stability. The basic

connections for measuring the loop gain are illustrated below.

Figure 4-1

Connections for loop gain measurement

The set up and measurement method for a typical DC-DC converter are explained below.

Figure 4-2

Example of connections for measuring the loop gain of a DC-DC converter

The injection resistance in the above diagram is inserted to prevent an open loop if the measurement probe

is removed from the circuit being measured. The resistance value is several tens of ohms or less and

sufficiently smaller than R1.
