چکیده
This paper introduces a detailed analysis for the operation of the transistor chain in CMOS gates. The chain is modeled by a transistor pair according to the operating conditions of the structure. The system of differential equations for the derived chain model is solved and analytical expressions which accurately describe the temporal evolution of the output voltage, are extracted. For the first time a fully mathematical analysis without simplified step inputs and linear approximations of the output waveform and without resistors replacing transistors, is presented. The final results for the calculated response and the propagation delay of this structure are in excellent agreement with SPICE simulations.
