A CMOS Semi-Custom Chip for Mixed Signal Designs
نویسنده
چکیده
This paper describes a redesign of a Sea-ofGates chip that was developed at Delft University of Technology more than 10 years ago, and that has extensively been used at laboratory courses since then. The main difference with the original chip is that the new one has several analog cells like OpAmps, comparators, and resistor banks in addition to a large core of Sea-of-Gates transistors. While the Sea-of-Gates transistors are mainly used to implement the digital parts of the design, the analog cells can efficiently be used to create analog subsystems like amplifiers and digital-to-analog converters. Similar as to the original Sea-of-Gates chip, the designer uses the OCEAN/Nelsis design system to generate two metallization layers to implement the design. Keywords— mixed-signal, semi-custom, IC, Sea-ofGates, analog cell array.

متن کاملDesign of a High-Speed UART VLSI Library Cell
We present the sampling and decoding algorithm and the VLSI implementation of a high-speed UART (Universal Asynchronous ReceiverTransmitter) library cell to be used in custom or semi-custom VLSI chip designs. Our approach to data recovery, which is based on signal preprocessing and an innovative decoding algorithm, operates with as few as 2 samples per bit time, thus achieving a high communicat...
متن کاملSoc Design Often Includes Analog and Mixed-signal Circuits. Understanding Some of the Challenges of These Devices Helps Engineers Develop a Successful Soc-design Strategy
CMOS was developed as a digitally friendly process. Now, thanks to high levels of system integration and the emergence of SOC (system-on-chip) design, CMOS has also become the process of choice for mixed-signal applications. However, cutting-edge CMOS has limitations in these applications. Process restrictions, inaccurate simulation models, wide parametric variance, and noisy application enviro...
متن کاملA Fully Integrated Range-Finder Based on the Line-Stripe Method
In this paper, an imaging chip for acquiring range information using by 0.35 μm CMOS technology and 5V power supply has been described. The system can extract range information without any mechanical movement and all the signal processing is done on the chip. All of the image sensors and mixed-signal processors are integrated in the chip. The design range is 1.5m-10m with 18 scales.
متن کاملA Hardware Realisation of a Block-based Disparity Estimator on a Cmos Sea-of-gates Semi-custom Chip
In this paper we describe a rst hardware realisation of a block-based disparity estimator which is suitable for real time applications with video speed. Since the quality of the calculated raw disparity elds will be rather poor, postprocessing steps are needed, but this is considered as a separate step. The circuit is implemented as an Application Speciic Integrated Circuit (ASIC) on a CMOS Sea...
