A Radiation Hardened 16 GS/s Arbitrary Waveform Generator IC for a Submillimeter Wave Chirp-Transform Spectrometer

This paper describes a radiation hardening design approach of a dual channel 16 GSps single chip arbitrary waveform generator (AWG) - a complex mixed-signal ASIC - that consists of a low phase noise 16 GHz PLL, two 1.6 Mbit SRAM blocks, two multiplexing chains, and two 4-bit DACs. The ASIC is dedicated to be a part of a submillimeter wave spectrometer that shall operate in deep-space environment. Under stringent power budget conditions, a selective radiation protection of the ASIC has been applied. The arbitrary waveform generator has been fabricated in a 130 nm SiGe BiCMOS process. Correct functionality has been verified in lab and will be further tested in an irradiation facility

A single chip 16 GS/s arbitrary waveform generator in 0.13 μm BiCMOS technology

This paper presents design considerations and measurements of a dual channel 16 GSps single chip arbitrary waveform generator. Each generator channel consists of a 1.6 Mbit SRAM block, a multiplexing chain, and a 4-bit DAC. A low phase noise 16 GHz PLL is integrated on the same chip. The prototype is designed to perform a lab experiment of a real-time SAW spectrometer. The overall power consumption of the chip is 1.45 W
