Abstract
A method of enhancing SAR ADC performance includes employing PVT processor to correct process, voltage and temperature (PVT) variation. The PVT processor senses process, supply voltage and temperature information then maximize the time for SAR binary search process. The PVT processor first applies coarse optimization to correct process and voltage variation then applies fine optimization to correct the temperature variation. The SAR ADC is operated at its optimized PVT condition and its performance is enhanced after PVT optimization.
