Litar yang menggunakan teknologi proses lanjutan perlu mengambil kira dengan betul variasi parameter peranti untuk mengoptimumkan prestasinya. Dalam kertas ini, formula analisis untuk menilai variasi kelewatan laluan litar CMOS Berbilang Ambang (MTCMOS) dicadangkan. Formula yang dicadangkan menyatakan kelewatan laluan dan variasinya sebagai fungsi parameter proses yang ditentukan oleh teknologi fabrikasi (voltan ambang, mobiliti pembawa, dsb.) dan parameter litar yang ditentukan oleh struktur litar (kapasiti beban setara dan pintu pensuisan serentak) . Dua prosedur untuk mendapatkan set parameter litar yang diperlukan dalam pengiraan formula yang dicadangkan juga ditakrifkan. Dengan formula yang dicadangkan, masa pengiraan variasi kelewatan laluan menjadi tiga pesanan lebih cepat daripada simulasi Monte-Carlo. Formula yang dicadangkan sesuai digunakan untuk reka bentuk litar MTCMOS yang cekap dengan mengambil kira variasi proses.

Abstract: Circuits utilizing advanced process technologies have to correctly account for device parameter variation to optimize its performance. In this paper, analytical formulas for evaluating path delay variation of Multi-Threshold CMOS (MTCMOS) circuits are proposed. The proposed formulas express path delay and its variation as functions of process parameters that are determined by fabrication technology (threshold voltage, carrier mobility, etc.) and the circuit parameters that are determined by circuit structure (equivalent load capacitance and the concurrently switching gates). Two procedures to obtain the circuit parameter sets necessary in the calculation of the proposed formulas are also defined. With the proposed formulas, calculation time of a path delay variation becomes three orders faster than that of Monte-Carlo simulation. The proposed formulas are suitably applied for efficient design of MTCMOS circuits considering process variation.
