In this paper we present a switched-capacitor matched filter for the satellite On-Board Data Handling (OBDH) Litton Coded bus. The proposed filter represents the analog frontend of the bus interface (modem) in the Central Data Management Unit (CDMU) and in each Remote Terminal Unit (RTU) of the satellite on-board communication system. The filter consists of(More)
This paper presents a 500 kBit/s modem for space applications, designed for interfacing the satellite equipment with the On-Board Data Handling (OBDH) bus system. The 28 mm 2 chip, fabricated in a 0.8 μm SOI radiation-hard CMOS process, achieves a bit-error rate as low as 10 –14 with 120 mV RMS of noise consuming 64 mW from a 5 V power supply.
