The Large Analog Bandwidth Recorder And Digitizer with Ordered Readout (LABRADOR) ASIC

Abstract

Three generations of full-custom analog integrated circuits designed for low-power, high-speed sampling of Radio-Frequency (RF) transients in excess of the Nyquist minimum have been developed. These 0.25$\mu m$ CMOS devices are denoted the Large Analog Bandwidth Recorder and Digitizer with Ordered Readout (LABRADOR) ASICs and finally consist of 9 channels of 260 deep sampling. Continuous sampling is provided with common stop capability. Input analog bandwidth is approximately 1GHz and sampling speeds are adjustable from 0.02 to 3.7GSa/s. Completely parallel internal conversion supports 12-bit digitization and readout of all 2340 cells in under 50$\mu s$.
