Design Note #27
Silicon wafer fabrication requires precision control of pressurized bladders during polishing operations. Fail-safe digital signal processing (DSP) together with high precision 24-bit analog instrumentation enable high-quality materials handling techniques.
Working with Texas Instruments’ TMS320C5471 ARM/DSP core, Orchid Technologies fashioned a robust DSP Core. Using Pulse-Width-Modulation (PWM) techniques, multi-channel, precision control of pressurized equipment can be achieved.
Twenty Four Bit high precision analog conversion electronics together with Pulse Width Modulation control systems form the control plane of this multi-channel pressure control system. Data conversion rates of 40KHz together with multi- channel PWM outputs enable high performance.
