Ultra High Speed

This paper presents an in-situ storage topology for ultra-high-speed burst mode imagers, enabling low noise operation while keeping a high frame depth. The proposed pixel architecture contains a 4T pinned photodiode, a correlated double sampling (CDS) amplification stage, and an in-situ memory bank. Focusing on the sampling noise, the system level trade-off of the proposed pixel architecture is discussed, showing its advantages on the noise, power, and scaling capability. Integrated with an AC coupling CDS stage, the amplification is obtained by exploiting the strong capacitance to the voltage relation of a single NMOS transistor. A comprehensive noise model is developed for optimizing the trade-off between the area and noise. As a proof-of-concept, a prototype imager with a 30 µm pixel pitch was fabricated in a CMOS 130 nm technology. A 108-cell memory bank is implemented allowing dense layout and parallel readout. Two types of CDS amplification stages were investigated. Despite the limited memory capacitance of 10 fF/cell, the photon transfer curves of both pixel types were measured over different operation speeds up to 20 Mfps showing a noise performance of 8.4 e−.

Abstract. A high-speed photo detector IC for application in Blu-ray/DVD/CD drives is presented. Bandwidths for the highest gain of 254 MHz and 221 MHz for 405 nm (Blu-ray) and 635 nm (DVD) wavelengths, respectively, were achieved by applying novel design methodologies. The combination of this outstanding speed performance with its low power dissipation of 192 mW at 5V supply and the low noise power of −72 dBm at 300 MHz makes it the best in literature reported optical transceiver IC for Blu-ray and Blu-ray/DVD/CD multi drives. Beside the excellent performance results, the usage of the novel design methodologies gave us an increased design efficiency with 25% compared to earlier similar design processes.

Healing Design

CMOS technologies are suffering from increased variability due to process, supply voltage and temperature (PVT) variations as we enter the tens-of-nanometer regime. Analog and mixed-signal circuits have failed to effectively exploit the high-speed and low-noise properties that deep scaled CMOS technologies provide due to marginality issues. Large variations in leakage current and threshold voltage also make highly integrated digital designs challenging. In addition, device aging introduces a temporal dimension to variations in circuit performance. Consequently, there is an increasing need for a new design methodology that can provide high yield and reliability under severe parametric variations. Although several post-silicon calibration and repair strategies have been proposed to address the PVT variations, no coherent design strategy for a SoC has been developed so far. We espouse a self-healing technique based on real-time sensing and built-in feedback due to its inherent advantage of dynamic adaptation to temporal variations. This tutorial paper outlines our vision of improving marginalities in deep scaled CMOS technologies using a generic and systematic self-healing design including a system-level auto-correction algorithm. It also illustrates this methodology with design examples.
