Common-Mode and Power Supply Rejection
The circuit shown in Figure 70 is used to measure the CMRR. The signal from the network analyzer is applied
common-mode to the input.
Figure 70. CMRR Test Circuit
Figure 71 is used to measure the PSRR of V

. The power supply is applied to the network analyzer’s
DC offset input. For both CMRR and PSRR, the output is probed using a high impedance differential probe
