  ABSTRACT: A third-order single-loop SC ΣΔ modulator is realized in a standard 90 nm digital CMOS technology. The modulator achieves 88 dB dynamic range for a 20 kHz signal bandwidth with an OSR of 100. Power consumption is 140 μW from a 1 V supply, and the chip core size is 0.18 mm².

  ABSTRACT: A 6-bit flash ADC with rail-to-rail input range is introduced in this paper. With the input range extension, the LSB is enlarged and the requirements for the component matching is released, reducing the sizes of transistors and the power consumption. Combined with the voltage interpolation technique, the power consumption can be reduced, further more. Simulated with a 0.18 μm CMOS technology file, the converter achieves 6-bit resolution with DNL and INL < 1 LSB up to 1GHz sampling frequency.
