N2 - This paper describes the design of a non-invasive blood glucose testing device. The Monte Carlo Pulsed Photoacoustic simulation of Figure 1 with the skin optic model in Figure 2 suggests we will need at least a signal to noise ratio (SNR) of 10 4. This SNR adequate to resolve 1 mili-Mole (mM) glucose variation in a 1 mm path length aqueous solution as wanted by ISO DIS 15197 5. The needed pixel signal to noise ratio (SNR) is achieved with in pixel differential gain amplifier which provides the pixel conversion gain in mV/e-. The normal CMOS imager typical conversion gain is a few μV/e-. Further, we substantial reduce the pixel noise to KT / 100 Cpd (Figure 5) with MIAO active pixel reset scheme. The prior art of pixel noise are KT / 30 Cpd (Pain active reset - Figure 4 Ref 7) and KT / 18 Cpd (Fowler active reset - Figure 3 Ref 6). Where Cpd is the pixel diode capacitance, K is Boltzmann constant and T is the temperature.
