Transformer-Coupled Front-End for Wideband A/D Converters

ADCs are being used at ever higher frequencies, making receiver front-end design increasingly important. Many applications are moving to super-Nyquist sampling in order to eliminate a mix-down stage, but amplifier noise will degrade the signal-to-noise ratio at these frequencies. Transformers can be used to replace the amplifier, minimizing noise and providing good high-frequency coupling.
