Abstract
A DC-DC converter for CMOS image sensors in bio-sensor chips is proposed. The DC-DC converter generates a PCP voltage, that is an on voltage of a pixel, and an NCP voltage, that is an off voltage of a pixel. The PCP voltage with a ripple voltage of within 1.33V is obtained from a positive charge pump of VPP (=5V) with a ripple voltage of 45.35 by using a regulator. Also, the NCP voltage with a ripple voltage of 0.05mV is obtained from a negative charge pump of VNN (=-2V) with a ripple voltage of 62.8 by using a regulator.
