An ASIC implementation of analogue receiver focused on telecommand applications for Category A missions (Return-to-Earth, lunar and even Lagrangian missions) is presented. In addition to embedded Low-Density Parity Check (LDPC) 128 bit analogue decoder, the ASIC integrates IF coherent demodulation, carrier tracking, clock recovery, SP-L to NRZ codify data conversion and telecommand-communication unit...
An original packaging method suitable for integrated thermal mass flow sensors is presented. The method is based on a polymethyl-methacrylate (PMMA) adapter, used to convey the fluid flow to the chip areas where the sensing structures are located. Sealing of the adapter was obtained by heating the chip itself to the PMMA glass transition temperature, in order to soften the adapter front surface and...
