Re-designed and re-simulated main LDO block for a power management IC. Verified the charge pump for the driver MOSFET outputs and examined bandgap reference circuit. Studied zero-crossing detection circuit for one of the DC-DC converters on the chip. Modified the circuit to produce the correct ZCD performance.

Wrote LabVIEW programs to connect a computer to bench test equipment for automated control and measurement. Studied DC-DC converter basics, learned operation of various bench test equipment, and manually validated the chip performance including line and load regulation, over/under-current/voltage, I2C communication, crosstalk, and circuit start-up sequence.
