The BIST method aims at full dynamic characterization of an ADC under test (DUT), while maintaining low area overhead. A low complexity DDFS hasbeen proposed in this paper and the design approach for BIST of ADC is discussed.doi:http://dx.doi.org/K.HARIHARAN...

This article will review the definition of dynamic range. Then, we’ll see that to efficiently utilize the dynamic range of an ADC, the amplitude of the input signal should be adjusted to the reference voltage of the ADC. ADC Dynamic Range The dynamic range is defined as the ratio between...
ratio (OSR) is the sampling rate divided by the Nyquist rate. The improvement in dynamic range (ΔDR) due to oversampling is ΔDR = log2(OSR) × 3 dB. For example, oversampling the ADC by a factor of four provides a 6-dB increase in dynamic range, or one additional bit of ...
point is normally specified. Typically, this gain compression occurs at a mixer level in the range of –5 to +5 dBm. Thus we can determine what input attenuator setting to use for accuratemeasurementofhigh-levelsignals3. Spectrum analyzers with a digital IF will indicate that ADC is over-...
the noise can be filtered to fs/(2 × OSR) to improve the dynamic range and SNR. In this case, the oversampled dynamic range is the ratio of the peak signal power to the noise power measured in the ADC output FFT from dc up to fs/(2 × OSR), where fs is the ADC sample rate...
A 1.0 V 77.5 dB Dynamic Range Delta-sigma ADC using Op-Amp Bias Sharing Technique A second-order single-bit delta-sigma analog-to-digital converter (ADC) is presented in this paper. An op-amp bias sharing technique is used to reduce the power consumption and active area of the ADC. It...
A variable gain digitization chain 102 suitable for use in a mobile phone having at least two possible gains in order to make the best possible use of the dynamic range of a, preferably 12-bit, analog-digital converter 103. This gain is switched as a function of the level of the signal...

Multilayer boards with separate ground and power planes produce the highest level of signal integrity. Consider the use of a split ground plane arranged to match the physical location of analog and digital grounds on the ADC's package. The impedance of the two ground planes must be kept as lo...
