Using RF-Transformer Based Drive Circuits
SLAS543A – MAY 2007 – REVISED SEPTEMBER 2007
Figure 81. ADC Input Impedance, Zin
For optimum performance, the analog inputs must be driven differentially. This improves the common-mode
noise immunity and even order harmonic rejection. An example of input drive using RF transformers is shown in
The single-ended signal is fed to the primary winding of the RF transformer. The transformer is terminated on the
secondary side. Putting the termination on the secondary side helps to shield the kickbacks caused by the
sampling circuit from the RF transformer’s leakage inductances. The termination is accomplished by two resistors
connected in series, with the center point connected to the 1.5 V common mode (VCM pin). The value of the
termination resistors (connected to common mode) has to be low (< 100
) to provide a low-impedance path for
the ADC common-mode switching current.
Figure 82 shows a configuration using a single 1:1 turns ratio transformer (for example, WBC1-1) that can be
used for low input frequencies up to 100 MHz.
