This article presents efficient, pass-transistor-based implementations of important digital functionality. The bottom line with pass-transistor logic is that you are trading electrical performance for the possibility of reducing transistor count. In the preceding article, we looked at a two-input AND gate consisting of only one transistor and one resistor. This certainly is a major reduction in component count compared to the typical CMOS two-input AND gate, which requires six transistors. If B is low, the upper transistor is in cutoff, but the output is not floating because the lower transistor, which is driven by the complement of B, provides a low-resistance path to ground. A lone NMOS can effectively transfer a logic-low signal from input to output, but it causes serious signal degradation when it attempts to transfer a logic-high signal. Now we need five transistors, versus six for the standard AND gate.
Show all documents However, it has as many as 28transistors and thus requires considerable chip area for its implementation. The circuit can operate with full output voltage swing. The designs were further reduced to only 16 transistors while maintaining the full output voltage swing operation. To further minimize the number of transistors, pass transistor logic can be used in lieu of transmission gate.

In electronics , pass transistor logic PTL describes several logic families used in the design of integrated circuits. It reduces the count of transistors used to make different logic gates , by eliminating redundant transistors. Transistors are used as switches to pass logic levels between nodes of a circuit, instead of as switches connected directly to supply voltages. Each transistor in series is less saturated at its output than at its input. By contrast, conventional CMOS logic switches transistors so the output connects to one of the power supply rails, so logic voltage levels in a sequential chain do not decrease. Simulation of circuits may be required to ensure adequate performance.
Section 3 describes a general method to synthesize basic two-input and three-input logic gates. (AND/NAND, OR/NOR, and XOR/XNOR) in each of these families.
