Design of NAND gate and NOR gate using Pass Transistor
Then the design of NAND and NOR gates using Pass transistor logic is explained.
Pass Transistor Logic - realization of NAND, NOR, AND, OR Gates using …
Pass transistor logic can be used to implement complex logic circuits. Pass transistor logic utilizes n-MOS transistors only. In pass transistor logic the primary inputs drive the gate terminals and source-drain terminal unlike static CMOS logic where primary inputs drive the gate terminal.
Sep 11, 2018 · What is the difference between the two circuits? How do voltage levels at the output of this gate differ from that of the pass-transistor multiplexer in the previous foil? How many transistors are needed? If not then it takes 6 transistors... Questions?

Pass-Transistor-Logic | Digital-CMOS-Design - Electronics Tutorial
The Pass transistor logic is required to reduce the transistors for implementing logic by using the primary inputs to drive gate terminals, source and drain terminals. In complementary CMOS logic primary inputs are allowed to drive only gate terminals.

Dec 26, 2018 · If a transmission gate has the input signal connected to the PMOS and the complemented input signal connected to the NMOS, it is an “active low” gate—it behaves like an open switch when the input is logic high and a closed switch when the input is logic low.
How to Make Logic Gates using Transistors
Sep 6, 2022 · In this post I have explained how to build NOT, AND, NAND, OR, and NOR logic gates using discrete transistors. The main advantage of using transistor logic gates is that they can work even with voltages as low as 1.5 V.
Basic Logic Gates in CMOS • Principles – Construct the nFET network using only nFETs and the pFET network using only pFETs. – If the output is 1, the pFET network connects 𝑉𝑉. 𝐷𝐷𝐷𝐷. to the output and the nFET network disconnects 𝑉𝑉. 𝑆𝑆𝑆𝑆. and the output. – If …

Dec 17, 2024 · A NOR Gate with two inputs can be build using two NPN transistor connected in parallel. Both transistor Q1, Q2 Base terminal will act as Inputs (A, B). Both Transistor collector terminal is connected to a pull-up Resistor (R3) and then to positive supply (Vcc).
When the logic gate shown is not a multiple-input NAND or NOR gate but has Characteristics 1, 2, 3, and 4 above, the gate will be referred to as a Complex Logic Gate
