Pmos circuit

CMOS Inverter – Circuit, Operation and Description. The CMOS inverter circuit is shown in the figure. Here, nMOS and pMOS transistors work as driver transistors; when one transistor is ON, other is OFF. This configuration is called complementary MOS (CMOS)..

The circuit designs are realized based on pMOS, nMOS, CMOS and BiCMOS devices. The pMOS devices are based on the p-channel MOS transistors. Specifically, the pMOS channel is part of a n-type substrate lying between two heavily doped p+ wells beneath the source and drain electrodes. ...In the event of a high input (1), the PMOS transistor is turned off, and the NMOS transistor is turned on, allowing the output to be low (0): The circuit above has two inputs and one output. Whenever at least one of the inputs is set high, the respective NMOS transistor will be switched off, while the PMOS transistor will be switched on.

sofd An inverter circuit outputs a voltage representing the opposite logic-level to its input. Its main function is to invert the input signal applied. If the applied input is low then the output becomes high and vice versa. Inverters can be constructed using a single NMOS transistor or a single PMOS transistor coupled with a resistor.Fig. 5.9: A PMOS transistor circuit with DC biasing.
