Analog Integrated Circuits Lab
Analog integrated circuits laboratory design course leverages the student's knowledge in the
fundamentals of electrical engineering circuit design through the design, analyze, simulate,
build breadboard, and testing of an analog integrated circuit. The projects requires that the
IC design must be DC coupled, the breadboard must use IC matched transistor pairs such as
CA3046 and CA3096, the IC design should contain current mirrors, differential stage, active
loads, voltage gain stage, output stage, and level shifter if appropriate for the IC design.
Throughout the ten week course the student will be required to propose the IC design type; use
and model matched transistor pairs; present IC design with stated performance goals; breadboard
any CE, CB, CC, cascode, or Darlington amplifier states; breadboard any differential amplifier
stages with resistor biasing; breadboard any current mirror circuits and active loads including
differential stages; breadboard any level shifter circuits and output stages; breadboard complete
IC and bench test. A complete test report comparing IC design performance goals to measured
performance will be submitted. This laboratory course is designed to be taken concurrently with
an Analog Integrated Circuits Course.
Integrated Circuit Course Procedure and Objectives
1. Student teams will design, analyze, simulate, construct breadboard, and test an
analog integrated circuit. Choose one of the following integrated circuits:
• Operational Amplifier
• Instrumentation Amplifier
• Voltage Follower / Buffer
• Voltage Comparator
• Voltage Reference
• Digital to Analog Converter
• Analog to Digital Converter
• Sample and Hold Amplifier
• Analog Switch / Multiplexer
• Phase Locked Loop
• Voltage Controlled Oscillator
• Other: Instructor approval is required
2. IC design must be DC coupled.
3. Breadboard must use IC matched transistor pairs such as CA3046 and CA3096.
4. IC design should contain the following building blocks (if applicable):
• Current Mirror
• Differential Stage
• Active Loads
• Voltage Gain Stage
• Output Stage
• Level Shifter
Typical Course Schedule
Week 1 - Form teams, brainstorm ideas, propose integrated circuit type
Week 2 - Use and model CA 3046 and CA 3096 matched transistor pairs or equivalent components
Week 3 n 4 - Develop IC design, testing criteria, and performance goals
Week 5 - Breadboard any common emitter, common base, common collector, cascode, or darlington amplifier stages
Week 6 - Breadboard any differential amplifier stages with resistor biasing
Week 7 - Breadboard any current mirror circuits and active loads including differential stages
Week 8 - Breadboard any level shifter circuits and output stages
Week 9 - Breadboard the complete IC, interconnect stages, and test
Week 10 - Team project completion requiring the following:
Complete testing and written report comparing IC design results to performance goals
Oral class presentation and bench top demonstration.
Note: It is highly recommended to perform component and breadboard level testing throughout each stage of the
IC design project.
