Dual Sampling-Based CMOS Active Pixel Sensor with a Novel Correlated Double Sampling Circuit
In this paper, we propose a 4-transistor active pixel sensor(APS) with a novel correlated double sampling(CDS) circuit for the purpose of extending dynamic range. Dual sampling techniques can overcome low-sensitivity and temporal disparity problems at low illumination. To accomplish this, two images are obtained at the same time using different sensitivities. The novel CDS circuit proposed in t...
متن کاملCurrent Mode Monolithic Active Pixel Sensor With Correlated Double Sampling for Charged Particle Detection
A monolithic active pixel sensor operating in current mode for charged particle detection is described. The sensing element in each pixel is an n-well/p-sub diode with a PMOS transistor integrated in an n-well. The drop of the n-well potential from the collection of charge modulates the transistor channel current. Each pixel features two current mode memory cells. The subtraction of distant-in-...
متن کاملCharge-based MOS correlated double sampling comparator and folding circuit
A novel charge-based comparator and folding circuit are presented. Correlated double sampling comparison is performed using a log-domain integrator, implemented by a subthreshold MOS transistor with the source coupled to a capacitor. The circuit produces a current that is a logistic function of the change in voltage on the gate, with an input-referred offset voltage that is a logarithmic functi...
متن کاملA High Speed CMOS Image Sensor with a Novel Digital Correlated Double Sampling and a Differential Difference Amplifier
In order to increase the operating speed of a CMOS image sensor (CIS), a new technique of digital correlated double sampling (CDS) is described. In general, the fixed pattern noise (FPN) of a CIS has been reduced with the subtraction algorithm between the reset signal and pixel signal. This is because a single-slope analog-to-digital converter (ADC) has been normally adopted in the conventional...
متن کاملCMOS Active Pixel Image Sensor
This paper addresses the development of a micropower 176 144 CMOS active pixel image sensor that dissipates one to two orders of magnitude less power than current state-of-the-art CMOS image sensors. The chip operates from a 1.5-V voltage source and the power consumption measured for the chip running from an internal 25.2-MHz clock yielding 30 frames per second is about 550 W. This amount enabl...
