DESIGN GOALS
• To design/build an active load with the following qualities:– Wide voltage compliance range– Very fast stepping rate– Wide range of settable currents– Unconditionally stable
Implementation Process
• Research Solutions• Choose Solution• Design Solution• Test Components• Design Review• Prototype Construction• Prototype Testing• Final Design Review• PCB Implementation
Sub-Circuits and Components• Power DAC
– Power DAC Current Sinking FET Network– Current Sense– Voltage Sense
• Power Management– Voltage Regulators
• Thermal Measurement– Current Source– High Accuracy Differential Amplifier
• Miscellaneous– Op Amp Buffers to Provide Circuit Isolation– MOSFET Switches– Pull-up/down Resistors
TEST MOTIVATION
• Component/Device Behavior
• Sub-Circuit Functionality
• Algorithm Functionality
• Sub-Circuit Functionality W/Algorithms
• Total Design Functionality
• Prototype Functionality
