1/f Noise Reduction using In-Pixel Chopping in CMOS Image Sensor
Kapil Jainwal, Mukul Sarkar
In this paper, an in-pixel chopping technique to reduce the low-frequency or 1/f noise of the source follower (SF) transistor in an active pixel sensor (APS) is presented. The SF l…
Localization: A Missing Link in the Pipeline of Object Matching and Registration
Deepak Mishra, Rajeev Ranjan, Santanu Chaudhury +2
Image registration is a process of aligning two or more images of same objects using geometric transformation. Most of the existing approaches work on the assumption of location in…
Unsupervised Despeckling
Deepak Mishra, Santanu Chaudhury, Mukul Sarkar +1
Contrast and quality of ultrasound images are adversely affected by the excessive presence of speckle. However, being an inherent imaging property, speckle helps in tissue characte…
Exploiting OxRAM Resistive Switching for Dynamic Range Improvement of CMOS Image Sensors
Ashwani Kumar, Mukul Sarkar, Manan Suri
We present a unique application of OxRAM devices in CMOS Image Sensors (CIS) for dynamic range (DR) improvement. We propose a modified 3T-APS (Active Pixel Sensor) circuit that inc…
Analysis and validation of low-frequency noise reduction in MOSFET circuits using variable duty cycle switched biasing
Kapil Jainwal, Mukul Sarkar, Kushal Shah
Randomization of the trap state of defects present at the gate Si-SiO interface of MOSFET is responsible for the low-frequency noise phenomena such as Random Telegraph Signal (…
