So the function of the PMOS transistor and NMOS transistor is quite opposite. If the gate terminal provides a 1 voltage, then this inverter will change it into zero and functions the circuit accordingly. So the main function of this circle is to invert the input voltage value. This bubble is also known as an inversion bubble. ![]() Similarly, this transistor forms a closed circuit when it gets a voltage at around 0 volts which means the current flows from the gate (G) terminal to the drain (D). This transistor will form an open circuit whenever it gets non-negligible voltage which means, there is no flow of electricity from the gate (G) terminal to the source (S). The p-type transistor working is quite opposite to the n-type transistor. PMOS Transistor Symbol How Does PMOS Transistor Work? The PMOS transistor symbols are shown below. In this transistor, the charge carriers like holes are responsible for the conduction of current. These transistors have three main terminals the source, the gate & the drain where the transistor’s source is designed with a p-type substrate, and the drain terminal is designed with an n-type substrate. This transistor is exactly the reverse of the NMOS Transistor. The PMOS transistor or P-channel metal oxide semiconductor is a kind of transistor where the p-type dopants are utilised in the channel or gate region. ![]()
