Cmos and gate theory
Field-effect transistors, particularly the insulated-gate variety, may be used in the design of gate circuits. Being voltage-controlled rather than current-controlled devices, IGFETs tend to allow very simple circuit designs. Take for instance, the following inverter circuit built using P- and N-channel IGFETs: See more The upper transistor is a P-channel IGFET. When the channel (substrate) is made more positive than the gate (gate negative in reference … See more The lower transistor, having zero voltage between gate and substrate (source), is in its normal mode: off. Thus, the action of these two transistors are such that the output terminal of the … See more Using field-effect transistors instead of bipolar transistors has greatly simplified the design of the inverter gate. Note that the output of this gate never floats as is the case with the … See more Next, well move the input switch to its other position and see what happens: This may cause a problem if the input to a CMOS logic gate is driven by a single-throw switch, where one state has the input solidly … See more Webfamily to another. 6.111 will use both TTL (Transistor-Transistor Logic) and CMOS (Comple-mentary Metal-Oxide Semiconductor) logic. The voltage ranges for the two logic families are not compatible. In this exercise, you will first measure the electrical characteristics of a TTL and CMOS gate using the circuit in Figure 1.

CMOS logic dissipates less power than NMOS logic circuits because CMOS dissipates power only when switching ("dynamic power"). On a typical ASIC in a modern 90 nanometer process, switching the output might take 120 picoseconds, and happens once every ten nanoseconds. NMOS logic dissipates power whenever the transistor is on, because there is a current path from Vdd to Vss through the load resistor and the n-type network.
