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.
