View Answer. Hence the NMOS is in cut-off and PMOS is in linear region and output voltage is VDD. b) high Increasing fan-out ____________ the propagation delay. advertisement. a) infinite on resistance c) high output capacitance The Questions and over here on EduRev! b) saturation Digital Microelectronic Circuits The VLSI Systems Center - BGU Lecture 4: The CMOS Inverter Operating Regions To Sum it up: 22 V out V in V DD V DD • Towards the rails, one of the transistors is cut off, and the other is resistive. c) very high Their value can be estimated as Saturated region (V gs-V t
