발표초록 :
I will present several unconventional data conversion architectures. First, I will talk about how we can make use of noise, which is usually deemed as an undesirable thing, to estimate the conversion residue and increase the SNR of a SAR ADC. It is an interesting example of stochastic resonance, in which the presence of noise can lead to not SNR degradation but SNR enhancement. Second, I will talk about how we can perform data conversion below the Nyquist rate by exploiting the sparsity of the input signal. I will show two example compressive sensing ADCs and how the effective ADC conversion rate can be reduced by 4 times but without losing information. Third, I will discuss hybrid ADC architectures, especially the combination of SAR and delta-sigma ADC. This novel noise-shaping SAR ADC can achieve high power efficiency and high resolution but without the need for any explicit amplifier. Last but not least, I will show our groups’ research on time/phase-domain delta-sigma ADCs that use simple logic gates for integration and quantization. They can not only achieve high performance and are scaling friendly, but also are fully synthesizable using standard digital flow, greatly improving productivity.
