The presence of a signal at frequency fs/2 on the reference will cause spectral components in the signal near fs/2 to mix down into the baseband. Especially in /spl Sigma/-/spl Delta/ modulator the output bit stream will contain large amounts of quantization noise at frequencies around fs/2 and the intermodulation should be minimized to the highest degree to avoid baseband destruction. In this paper a systematic way where a modulator transfer function is modified to reduce intermodulation effect is proposed. Simulations show the effectiveness of the method.","PeriodicalId":313978,"journal":{"name":"Proceedings of Second IEEE Asia Pacific Conference on ASICs. AP-ASIC 2000 (Cat.

The proposed architecture reduces the local oscillator frequency to half, which enables the integration on a single chip and reduces the overall power consumption.

Formal equivalence checking is used to verify if BIST signals are correctly integrated into an ASIC. Static Timing Analysis (STA) is used to verify BIST timing. Two ASICs, implemented using 0.25 /spl mu/m technology, are used to apply static-based verification methodologies. Our experimental results show that static-based verification achieves significant verification speedup compared to simulation. This allows fast and early detection of function and timing errors that may be introduced during BIST integration:.","PeriodicalId":313978,"journal":{"name":"Proceedings of Second IEEE Asia Pacific Conference on ASICs.

Since most IPs are provided by different vendors, they have different interface schemes and different operating frequencies. In this paper, we propose a new interface synthesis method that enables one not only to handle the interface between IPs with different operating frequencies but also to minimize the hardware resource required for the interface. We have demonstrated the proposed algorithm by applying it to a real design example, MP3 decoder, and verified the IIS-to-PCI protocol converter on a real hardware system.","PeriodicalId":313978,"journal":{"name":"Proceedings of Second IEEE Asia Pacific Conference on ASICs.
