In electronic terms, the working principle of a transistor is very simple: it has three main terminals, and the current flowing through one of its terminals can be controlled by the voltage between the other two terminals. In the case of a MOSFET, the voltage between the gate and the source ports controls the current flowing through the drain. The ...
There are two types of MOSFETs: the NMOS and the PMOS. The difference between them is the construction: NMOS uses N-type doped semiconductors as source and drain and P-type as the substrate, whereas the PMOS is the opposite. This has several implications in the transistor functionality (Table 1). The most evident one is the drain current direction ...
Although the transistor operation can be described by the gate, drain and source, the MOSFET is actually a 4-pin device. The fourth port is called body, and it is connected to the substrate of the transistor. If the voltage between the body and the source is different from zero, the transistor will suffer from the body-effect. The body-effect chang...
MOS transistors are built on top of silicon wafers. This process uses semiconductor doping and oxide growth to create N-type, P-type and insulating regions in a layer-by-layer fashion. Geometric shapes are obtained via photolithography and chemical etching. A simplified illustration of the NMOS and PMOS cross-section can be seen in Figure 4. Figure...
It is difficult to cover every application of the NMOS and PMOS, as they can be used as active loads, voltage-controlled resistors, transimpedance amplifiers, current mirrors and even capacitors and diodes. Thus, we will focus on the most popular applications: voltage amplifiers and switches. However, the same reasoning used here can be applied to ...
Learn about the MOSFET, a widely used transistor in electronics, and its two main forms: NMOS and PMOS. Understand the operation modes, models, characteristics and differences of NMOS and PMOS, and how they are used in amplifiers and switches.
NMOS is a national-level math contest for primary school students organised by NUS High School. It covers topics at primary 5 level and requires school registration. Learn more about the competition and MathsHub's enrichment programmes.
NMOS or nMOS logic (from N-type metal–oxide–semiconductor) uses n-type (-) MOSFETs (metal–oxide–semiconductor field-effect transistors) to implement logic gates and other digital circuits. NMOS transistors operate by creating an inversion layer in a p-type transistor body.
