Wideband A/D Converter Front-End Design Considerations

A factor often overlooked when using transformers in the front-end circuitry of high-speed A/D converters is that they are never ideal. Any imbalance introduced by the transformer delivers an imperfect signal to the ADC, causing overall performance to be worse than the ADC could otherwise provide. Read about the effects of input imbalances on ADC performance and circuitry that can help achieve better results.
