A Self-checking Current-mode Analogue Memory
A long-term analogue memory based on continuous-time, current-mode algorithmic A/D-D/A converters is presented. It achieves an efficient performance in terms of speed, resolution, power, and area, while incorporating self-checking capability. Its operation is described and illustrated with experimental results of a CMOS-2.4μm prototype with 7bit resolution. INTRODUCTION Long-term storage of ana...
متن کاملIntegration of asynchronous and self-checking multiple-valued current-mode circuits based on dual-rail differential logic
A new multiple-valued current-mode (MVCM) integrated circuit based on dual-rail differential logic, whose currentdriving capability is high at a low supply voltage, is proposed to realize a totally self-checking circuit and an asynchronous-control circuit. Two nMOS transistors with different threshold voltages are used as complementary pass switches in the proposed differential-pair circuit (DP...
متن کاملComparative Accuracy Study of Current-Mode versus Voltage Mode Analog Memory in 0.25μm Technology
The aim of this work is the study of switched-current and voltage-mode memory cells in order to develop a model including non-ideal effects such as charge injections, nonlinear capacitance and readout system influence. These models will allow non-linearity control regard to surface, speed and power criteria in digital dedicated submicrometer technology. Such models lead to a memory cell optimiz...
متن کاملSCAMP-3: A Vision Chip with SIMD Current-Mode Analogue Processor Array
In this chapter, the architecture, design and implementation of a vision chip with general-purpose programmable pixel-parallel cellular processor array, operating in single instruction multiple data (SIMD) mode is presented. The SIMD concurrent processor architecture is ideally suited to implementing low-level image processing algorithms. The datapath components (registers, I/O, arithmetic unit...
متن کاملSelf-timed is self-checking
Self-checking circuits detect (at least some of) their own faults. We describe self-timed circuits, including combinational logic and sequential machines, which either halt or generate illegal output if they include any single stuck-at faults. The self-timed circuits employ dual rail data encoding to implement ternary logic of 0, 1, and unde f ined states; the fourth state is used to signal ill...
