چکیده

A sine waveform signal generator for the on chip testing of mixed-signal circuits for speech processing is present. The idea behind is to attenuate the higher frequencies in a periodic triangular waveform. The hardware implementation is discussed. And the simulation results validate our proposal. This generator can be employed for both the digital BIST and the analog/mixed-signal BIST applications with a verified DAC together. Index terms : Signal Generator, BIST, MixedSignal Circuit, Test

Reliability and Performance Evaluation of Fault-aware Routing Methods for Network-on-Chip Architectures (RESEARCH NOTE)

Nowadays, faults and failures are increasing especially in complex systems such as Network-on-Chip (NoC) based Systems-on-a-Chip due to the increasing susceptibility and decreasing feature sizes. On the other hand, fault-tolerant routing algorithms have an evident effect on tolerating permanent faults and improving the reliability of a Network-on-Chip based system. This paper presents reliabili...

Half-sine and triangular despreading chip waveforms for coherent delay-locked tracking in DS/SS systems

The performance of a coherent delay-locked tracking scheme for direct-sequence/spread-spectrum systems using half-sine or triangular chip waveforms for early and late despreading sequences is analyzed. The effect of band-limiting on the received signals is considered. Mean time to lose lock (MTLL) and root mean square (rms) tracking error of the delay-locked loop (DLL) are compared with that of...

Generalized multicarrier DS-CDMA using various chip waveforms

In this contribution the family of generalized multicarrier DS-CDMA (MC DS-CDMA) schemes [1] is investigated, when considering time-domain half-sine and raised-cosine chip waveforms, in addition to the rectangular chip waveform. Our results show that for a given subcarrier spacing the particular choice of the chip waveform has a substantial influence on the system’s performance. However, in the...
