This paper compares the performance of three low drop-out (LDO) voltage regulators (simple LDO, LDO with common-source, and LDO with source-follower) in load regulation and transient response. The regulators are designed in 1.6 /spl mu/m technology with three different error amplifier designs to investigate the regulating performance. The performance of(More)
This paper presents a successive approximation ADC (SAR) architecture that takes advantage of the signal-dependent photon shot-noise characteristic of an image sensor. The multi-segmented successive approximation ADC (MS-SAR) applies the sub-ranging technique, where each segment’s conversion step size is scaled according to the photon transfer curve (PTC)(More)
