Figure 6. PSRR measurement setup for amplifier. (a) Calibration setup, (b)
PSRR setup.
As shown in Figure 6, the amplifier input is grounded, either AC or DC ground,
for PSRR measurement. Calibrate the setup as shown in Figure 6a with the
network analyzer input-A and input-B connected to the same point at the
amplifier's supply input. After calibration, move input-B to the amplifier output
as shown in Figure 6b. Then measure PSRR in the same way as the LDO in the
previous section.
