This paper introduces the design and realization of a multi-channel high-speed waveform generator based on FPGA, Which consists of the high-speed clock generator, the high-speed high-precision digital to analog converter, multi-stage pipeline accumulator and high-speed small signal conditioning. At last, it gives some simulation. The results show that the output signal type of this waveform generator is rich, and the maximum output frequency is 80MHz. The waveform generator can be used in the fields which require multi-channel high-speed signal, such as phased array radar.

Binary Weighted

We present a method to realize a low-power and high-speed digital-to-analog converter (DAC) for system-on-chip applications. The new method is a combination of binary-weighted current cells and R-2R ladder and is specially suited for modern BiCMOS technologies. A prototype 5 GS/s DAC is implemented in 0.13 μm SiGe BiCMOS technology. The DAC dissipates 26 mW and provides an SFDR higher than 48 dB for output frequencies up to 1 GHz.

This Paper describes ionizing irradiation effects and annealing behavior on some commercial available CMOS high speed and high resolution Digital-to-Analog Converter —AD9742. AC and DC parameters are measured before and after radiation and annealing experiment. Results show that DC parameters are more sensitive than AC parameters, and all parameters are fully recovered after room-temperature and elevated-temperature annealing behaviors. Test facilities, results and analysis are presented in this paper in details.

Arbitrary Waveform

High speed arbitrary waveform generator enabled by photonic digital to analog converter where the bandwidth limitation arising due to interconnect and device parasitics in its electronic counterparts is circumvented. Leveraging the silicon photonic integration technology for this purpose provides a potential high resolution, high bandwidth, and energy efficient solution for signal transmitters.
