I'm trying to design an ADC in subthreshold region of operation of the MOSFET. It should consume least amount of power.
I searched the web and found ADC types - SAR, Wilkinson, Dual-slope, ∑-Δ, Flash, etc. I also found a paper entitled "An 8-Bit Single-Ended Ultra-Low-Power SAR ADC With a Novel DAC Switching Method and a Counter-Based Digital Control Circuitry" from IEEE. The ADC they designed consumes 101 nW power. I haven't fully read the paper but I understand SAR ADC requires extra hardware like an additional controller etc.
So my question is - which type of ADC I should design? :-?
