Pass transistor
WebBut, it’s important to note that the PMOS pass element isn’t ideal for extremely low voltage devices. Also, you can get a low dropout voltage, output, and input with the NMOS transistor. The pass element-based (NMOS) LDO benefit is that the regulator’s output resides in the transistor’s source. http://www.ee.ic.ac.uk/pcheung/teaching/ee4_asic/notes/Lecture%2011%20-%20Pass%20Transistor%20Logic.pdf

Web10 Jan 2016 · In the figure below, the pass transistor should begin operating as soon as the LM317 current becomes approximately 1 ampere, because of the voltage drop across the 0.7 ohm resistor. Current restricting transpires at roughly around 2 amps for the LM317 which is able to shake off around 1.4 volts over the 0.7 ohm resistor and then generate a …
WebIn the figure below, the pass transistor will start conducting when the LM317 current reaches about 1 amp, due to the voltage drop across the 0.7 ohm resistor. Current limiting occurs at about 2 amps for the LM317 which will drop about 1.4 volts across the 0.7 ohm resistor and produce a 700 millivolt drop across the 0.3 ohm emitter resistor.

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 … See more Pass transistor logic often uses fewer transistors, runs faster, and requires less power than the same function implemented with the same transistors in fully complementary CMOS logic. XOR has the worst … See more Static and dynamic types of pass transistor logic exist, with differing properties with respect to speed, power and low-voltage operation. As integrated circuit supply voltages decrease, the disadvantages of pass transistor logic become more … See more The pass transistor is driven by a periodic clock signal and acts as an access switch to either charge up or charge down the parasitic capacitance Cx, depending on the input signal Vin. … See more Some authors use the term "complementary pass transistor logic" to indicate a style of implementing logic gates that uses transmission gates composed of both … See more • Weste; Harris (2005).
