Transformer Coupled Circuits
Figure 3 shows the analog input being driven by an RF
transformer with a center-tapped secondary. The center
tap is biased with VCM, setting the A/D input at its optimal
DC level. At higher input frequencies a transmission line
balun transformer (Figures 4 to 6) has better balance,
resulting in lower A/D distortion.

Amplifier Circuits
Figure 7 shows the analog input being driven by a high
speed differential amplifier. The output of the amplifier is
AC-coupled to the A/D so the amplifier’s output common
mode voltage can be optimally set to minimize distor-
tion.
At very high frequencies an RF gain block will often
have lower distortion than a differential amplifier. If the
gain block is single-ended, then a transformer circuit
(Figures 4 to 6) should convert the signal to differential
before driving the A/D.
