Lecture
This lecture focuses on semiconductor components, specifically analyzing the behavior of transmission gates formed by parallel connections of NMOS and PMOS transistors. The instructor begins by correcting exercises from a previous series, leading into a detailed examination of the third exercise. The discussion includes the relationship between current and voltage in an NMOS transistor with short-circuited gate and drain, and how to determine the threshold voltage from the characteristic curve. The lecture also covers the truth table for the transmission gate, explaining the necessity of the PMOS transistor for proper signal transmission. The instructor illustrates how the NMOS conducts zeros while the PMOS conducts ones, allowing for effective signal control between input and output. The concepts are reinforced through schematic representations and practical examples, ensuring a comprehensive understanding of the operation of these semiconductor devices.
