Comparison of Several Ramp Generator Designs For Column-Parallel Single Slope ADCs

چکیده
Many CMOS image sensors now use columnparallel readout structure with single slope ADCs. Ramp generator in the ADCs is a critical building block since the performance of the ADCs depends a lot on the accuracy of the ramp signal. In this paper, we present several ramp generator architectures and compare their performance in terms of resolution, area, noise and reliability.

A distributed ramp signal generator of column-parallel single-slope ADCs for CMOS image sensors
This paper proposes a distributed ramp signal generator of column-parallel single-slope ADCs for CMOS image sensors. This architecture does not require any power-hungry amplifiers of the conventional one but consists of miniaturized column-wise ramp signal generators connected together by metal wires, which achieves high linearity and high uniformity. Simulation results show less than 1LSB nonl...

This work presents a hybrid column-parallel TDC-interpolated Single-Slope ADC which uses a digital feedback to solve the delay element and clock period matching problem in Flash TDC-Interpolation of SS ADCs. The presented feedback correction scheme is applied in-column and occurs online after the end of each conversion, occupying less than 5% of the ramp time at 12-bits. The concept of the arch...
متن کاملVery Linear Ramp-Generators for High Resolution ADC BIST and Calibration
Two very linear ramp-generator designs are presented. The circuits are to be used in high-resolution ADC built-in-self-test (BIST) and on-chip calibration. The first design is to charge a capacitor by a small current, which is linear enough to test 14-bit ADCs. The second design is in a relaxation oscillator architecture. It is linear enough to test up to 12-bit ADCs. The two designs have been ...
