A low-noise monolithic CMOS bio-potential dectector (2009)
Fung, Sheung Wai, Liu, Bing, Yuan, Jie, Guo, Qing
Bio-potential detection is important for bio-medical diagnostics and research. Bio-potentials are generally weak (μV) with high offsets (100mV level). Low noise processing is critical to extract the...
Digital calibration technique for highly linear wide dynamic range CMOS imaging sensor (2009)
Yuan, Jie, Chan, Ho Yeung, Fung, Sheung Wai, Liu, Bing
A novel digital calibration scheme is developed to improve the linearity of a wide dynamic range (DR) CMOS imaging sensor, with a low calibration overhead. Experimental results show that the...
