Analog Architecture Complexity Theory Empowering Ultra-Low Power Configurable Analog and Mixed Mode SoC Systems

Look up Table Based Low Power Analog Circuit Testing

In this paper, a method of low power analog testing is proposed. In spite of having Oscillation Based Built in Self-Test methodology (OBIST), a look up table based (LUT) low power testing approach has been proposed to find out the faulty circuit and also to sort out the particular fault location in the circuit. In this paper an operational amplifier, which is the basic building block in the ana...

Fault diagnosis in analog and mixed mode low testability system

This paper describes our views on how to detect faults in low testability analog or mixed mode (analog electro-mechanical) system. A new method is developed to identify a minimum number of faulty parameters in the system with ambiguities. From sensitivity analysis of the system, we can extract solution invariant matrix and identify singular cofactors of this matrix. The approach can be extended...

Characterization of Tunnel Fet for Ultra Low Power Analog Applications

In modern portable devices, the supply voltage is decreased to reduce the power dissipation. However as the supply voltage is scaled down below 0.4V, the normal MOSFET devices cannot be used due to lower ION/ IOFF ratio which will reduce the static power dissipation. Hence for low power applications, Tunnel FET is used as alternatives due to their higher sub threshold swing, extremely low off s...

A Low Complexity and Low Power SoC Design Architecture for Adaptive MAI Suppression in CDMA Systems

In this paper, we propose a reduced complexity and power efficient System-on-Chip (SoC) architecture for adaptive interference suppression in CDMA systems. The adaptive Parallel-ResidueCompensation architecture leads to significant performance gain over the conventional interference cancellation algorithms. The multi-code commonality is explored to avoid the direct Interference Cancellation (IC...
