Catalog Description

Diode and transistor models used in logic gates. Dynamic behavior of logic gates: fall-time, rise-time, propagation delay. n-type metal–oxide–semiconductor (NMOS)-based and complementary metal–oxide–semiconductor (CMOS)-based logic gates: inverters, Not-AND (NAND), and Not-OR (NOR) gates. Static and dynamic memory circuits. Bipolar junction transistor- (BJT-) based logic gates: Emitter-coupled logic (ECL) and transistor-transistor logic (TTL). Digital-to-analog (D/A) converters. Experiments on diode- and NMOS-based logic gates, timer circuits, and TTL.

Course Objectives

The goal of this course is to provide the basic principles of digital circuits emphasizing their transistor-level implementations. The course will also enable the students to understand the operation of fundamental digital integrated circuits such as inverters, random access memory (RAM) and read-only memory (ROM) circuits, emitter-coupled logic (ECL), transistor-transistor logic (TTL), and digital-to-analog converters.

Course Learning Outcomes

Upon successful completion of this course, students will be able to:
(1) Recognize the diode and transistor models in logic gates to understand key performance parameters,
(2) Describe the working principles of NMOS-based and CMOS-based logic gates, including inverters, NAND, and NOR,
(3) Apply transistor knowledge to design and analyze static and dynamic memory circuits,
(4) Analyze BJT-based logic circuits, such as TTL and ECL, understanding behavior and applications,
(5) Assess the functioning and performance of digital-to-analog converter circuits considering accuracy and resolution,
(6) Collaborate in conducting experiments involving diode- and NMOS-based logic gates, timer circuits, and TTL.
