Electrical Engineering
The project outlined in this report is the design, layout, and routing of a linear voltage regulator using Cadence VLSI (very-large-scale integration) software. The design specifications for this regulator are as follows: input voltage range of 5V + 1V, load current capabilities of 150mA, and output voltage range of 1.15V to 3.3V. Furthermore, the design of this circuit was broken into three main sub-circuits: an error amplifier, bandgap reference circuitry, and biasing circuitry for the bandgap. Together, these sub-circuits integrated to make the final design.
Research for different topologies for a voltage regulator was done and the Brokaw bandgap reference …
