Developed 3 generations of embedded waveform generators. System consisted of state machine controlled flash memory directly driving 50 MHz 16 bit DAC. First generation: two interleaved parallel NOR flash.  Second generation: four interleaved parallel NAND flash.   Third generation: four SPI serial flash using quad channel output. System can provide 8 million sample waveform at 50MHz.

Generator is used in control ion ejection of in a mass spectrometer trap.

Responsibilities included design, schematics, PCB layout, performance verification and initial state machine implementations in CPLD/FPGA.
