It is conjectured that the covariance matrices minimizing the outage probability under a power constraint for multiple-input multiple-output channels with Gaussian fading are diagonal with either zeros or constant values on the diagonal. In the multiple-in ...

Ultra-low power (ULP) biomedical implants and sensor nodes typically require small memories of a few kb, while previous work on reliable subthreshold (sub-Vt) memories targets several hundreds of kb. Standard-cell based memories (SCMs) are a straightforwar ...
Density, speed and energy efficiency of integrated circuits have been increasing exponentially for the last four decades following Moore's law. However, power and reliability pose several challenges to the future of technology scaling. Approximate computin ...
A troubleshooting method for debugging wireless sensor nodes using measurements of the supply current waveform and logic outputs is presented. The troubleshooting and debugging technique uses the supply current waveform in conjunction with the measurement ...
In this paper, two circuits are proposed to implement tri-state buffers/bus drivers for MOS Current-Mode Logic digital circuits. The first is a switch-based, fully differential circuit, while the second is a voltage follower-based, pseudodifferential circu ...
