Clock skew analysis based on NBTI degeneration of pMOSFET

Abstract

In this paper, a set of formulas which are sensitive to the shift in threshold voltage (AV<inf>th</inf>) of PMOS transistor, load capacitance (C<inf>L</inf>), and input transition (ti) have been explored to calculate the propagation delay of CMOS inverter using curved surfaces fitting. Different from conventional of focusing on load capacitance and input… (More)
