The key research questions that we target here are:
1. How can we settle the trade-off between large sinal bandwidth and power-efficiency?
2. What are the key SDM architectural choices that increase signal bandwidth, maintain low powe consumption, while achieving a compatitive linearity to the Nyquist ADC?
Our key research hypotheses are:
1. SDM with low OSR;
2. Multi-bit SDM;
3. Power efficient quantizers.
