Thus, the propagation delay times TPHL and TPLH are found from Fig. Physics. The maximum and minimum logic levels of a static CMOS inverter depends on : The size of the transistors. /F15 10 0 R << 14 0 obj In advanced CMOS, channel length can be fabricated at less than one micron. Topics 1 Static behavior 2 Dynamic behavior 3 Inverter chains João Canas Ferreira (FEUP)CMOS InvertersMarch 2016 2 / 31. For 11->01 we have 1 pMOS to charge THE SAME capacitor. NMOS are considered to be faster than PMOS, since the carriers in NMOS, which are electrons, travel twice as fast as the holes. The load capacitance CL can be reduced by scaling. In the above figure, there are 4 timing parameters. /ExtGState << Does it have to do with the functionality of the BJTs, or the architecture of the device itself?
