A 120nW 8b Sub-ranging SAR ADC with Signal-Dependent Charge Recycling for Biomedical Applications

We present an 8-bit sub-ranging SAR ADC designed for bursty signals having long time periods with small code spread. A modified capacitive-DAC (CDAC) saves previous sample’s MSB voltage and reuses it throughout subsequent conversions. This prevents unnecessary switching of large MSB capacitors as we...
