We present the IDE1060, an integrated circuit (IC) with 34 preamplifiers for reading out infrared (IR) sensors and focal plane imaging arrays (FPA). We designed the circuit under contract with the European Southern Observatory (ESO) where the device shall be used with typical large format astronomical IR sensors, e.g., Raytheon Aquarius and Teledyne HAWAII-2RG. The IDE1060 is intended to replace the fast readout amplifiers described in Ref. [1]. The circuit is designed for extreme operational environmental conditions: cryogenic to room temperature, latch-up immunity and high energy threshold for single event upsets from ionizing radiation. Based on the design methods we expect the circuit to be suitable for space-borne astronomical instruments as well. The device is manufactured in Q1 2018 and characterization is planned for the remainder of the year.
Summary
The attached figure and table summarize functions and key features of the IDE1060. The IDE1060 has 34 differential voltage-amplifying channels with a gain that is programmable in 8 steps from 2 to 16 (6dB to 24dB). The differential channel outputs can be connected to cables with large capacitances (several hundred pF) or used with external operational amplifiers and resistors to form classical three-amp instrumentation amplifiers. The chip contains one standalone amplifier that can be configured externally for different applications or debugging purposes. The chip also provides a temperature sensor. The IC operates at a nominal supply voltage of 3.5V and dissipates about 20 mW per channel at 77K. Various power-down modes are available for applications with less than 34 channels. The IDE1060 is latch-up immune and SEU-tolerant. The IC has been designed in a 0.35-µm CMOS process, and it is available in a CQFP208 package or as bare die (5.62mm x 11.64mm).
