摘要： A pipelined Analog-to-Digital Converter (ADC) stage includes a main sampling path having a first filter in series with a first sample and hold circuit and a sub-ADC sampling path having a second filter in series with a second sample and hold circuit driving a sub-ADC connected to a sub-Digital-to-Analog Converter (DAC). The frequency response of the main sampling path is matched to a frequency response of the sub-ADC sampling path such that a residue signal of the pipelined ADC stage stays within range.

摘要： A reference buffer amplifier within an integrated circuit includes a first output terminal connected to a first bond pad, the first bond pad being connected to a first external pin of the integrated circuit chip, the first external pin to allow an external capacitance to be connected to the output terminal. The reference buffer further includes a variable, settable resistance sub-circuit connected to a second bond pad, the second bond pad also being connected to the first external pin. The resistance sub-circuit is configured to be set to exhibit a resistance value to critically dampen a response of the reference buffer amplifier.
