Design and Analysis of Built-In Testers for CMOS Switched-Current Circuits
This paper presents the design and analysis of a built-in tester circuit for MOS switched-current circuits used in low-voltage/low-power mixed-signal circuits/systems. The use of the tester can reduce the test length significantly. The developed tester ...
The Concept of Operational Rank Extractor
An operational rank extractor (ORE) is introduced in this paper as an operational amplifier having rank extractors at its inputs. This versatile building block can implement a variety of nonlinear transfer functions such as a dead-zone amplifier, a ...
CMOS Design of a Current-Mode Multiplier/Divider Circuit with Applications to Fuzzy Controllers
Multiplier and divider circuits are usually required in the fields of analog signal processing and parallel-computing neural or fuzzy systems. In particular, this paper focuses on the hardware implementation of fuzzy controllers, where the divider ...
An Analog VLSI, Scale Invariant Method for Edge Detection
A simple technique for detecting adjustable contrast in a visual scene is presented. The circuit elements can be used to detect contrast in any array of sensors or processing elements where spatial relationships among neighboring elements define ...
An Improved Silicon Neuron
We describe an improved spiking silicon neuron (SN) [6] that approximates the dynamics of ionic currents of a real nerve cell. The improved version has less circuitry and fewer parameters than previous circuits thereby improving the spiking ...
Statistical Design of Low Power Square-Law CMOS Cells for High Yield
A robust design of low voltage low power square law CMOS composite cells using statistical VLSI design techniques is presented. Since random device/process variations do not scale down with feature size or supply voltage, the statistical design of low ...
