Bjt logic gates vs mosfet logic gates
WebMOSFET is a low power consumption but switing time is faster in the case of BJT. It is interesting to note that best achievable gm/C has order 1/t , t being carrier transit time … WebJan 15, 2024 · Logic gates are classified into logic families: Architectural paradigms used to systematically design circuits. The most intuitive logic families are based on a driver–load architecture, and they can be built using BJT or MOSFET. These logic families are collectively known as ratioed logic. Ratioed logic gates have excellent area and are ...

http://hyperphysics.phy-astr.gsu.edu/hbase/Electronic/trangate.html WebOct 21, 1999 · "In a logic-gate arrangement, each of the MOSFETs works like a switch. The switch is closed, or the MOSFET is turned on, if electric current can flow readily from the source to the drain.
WebBipolar transistors are better for low-voltage design. True. Transconductance in a CMOS device increases as the square of the gate voltage above the threshold. If the gate … WebMay 22, 2024 · Here is how it works: If the logic input voltage is zero, there will be no base current. This means that there will be no collector current and therefore the LED will be off. At this point the BJT is in cutoff. In contrast, when the logic level goes high, all of the logic voltage drops across \(R_B\), with the exception of \(V_{BE}\).
