Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: A comparator-based circuit that uses switched-capacitor charging replaces the op amp in the multiplying digital-to-analog converter (MDAC) of a low-voltage algorithmic ADC. MDAC output swing beyond Vdd allows greater than rail-to-rail ADC input range. At a supply voltage of 0.55 V, the ADC achieves 8.4 bit ENOB and 1.4 Vpp differential input range. It occupies 0.65 mm2 in 0.25-μm CMOS and dissipates 0.79 μW at a 5 kHz conversion rate, which is low due to the near-Vt supply voltage.
