Wired Communication

A new transceiving protocol is designed for an FSO communication system, and it’s discussed from the transmitting protocol and the receiving protocol. Different from wired communication, a FSO system modulates the data on a narrow beam of laser transmitting through the free space or the atmosphere, and the protocol is optimized for terrestrial FSO links. Due to the complex composition and activity of the atmosphere, this signal channel brings in great influence on the transmitting laser in it. The function of the receiving protocol includes filtering and synchronizing the input serial data stream, paralleling the serial data stream, decoding the input data, error checking, and exception handling and interfacing the outer receiver with a parallel port. The transceiving protocol could be programmed into a single FPGA chip to improve system integrity and reduce the system cost. We also test the hardware platform and communication protocol and give the waveform. The experiment and Simulation prove that the protocol presented can work well at a certain bit rate scale.

Low Power Electronics

An increasing number of industries are calling for low power electronics that operate reliably at temperatures of 175°C and higher. Many of these applications require a precision data acquisition signal chain in order to digitize analog data so that it can be collected and processed. We have previously presented a new 600 kSPS SAR ADC that is rated at 210°C to meet these needs. However, the design of the supporting circuitry for a SAR ADC to achieve optimum performance is not trivial, especially over this wide temperature range. In this work we discuss the design of a complete data acquisition circuit building block that will take an analog sensor input, condition it, and digitize it to an SPI serial data stream. We will also discuss some of the practical aspects of fabricating the circuit to survive this harsh environment. This circuit reference design will be published and available off the shelf to designers of harsh environment systems.
