Switched-capacitor Litton-code matched filter for satellite ODBH bus
نویسندگان
چکیده
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 a 16-taps switched-capacitor FIR structure, implemented using a mixed serial/parallel architecture which allows optimal performance to be achieved with a minimum number of components. Simulation results confirm the validity of the proposed approach. The complete modem is being integrated in a 0.8 μm BiCMOS, SOI, radhard technology.

A Sub-µW Tuneable Switched-Capacitor Amplifier-Filter for Neural Recording Using a Class-C Inverter
A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...
متن کاملA Very Low Voltage 9th Order Linear Phase Baseband Switched Capacitor Filter (RESEARCH NOTE)
A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...

In this paper, a modified auto zeroed integrator is used to design and simulate a low-voltage high-Q switched capacitor pseudo 2-path filter. The filter is a sixth–order Chebyshev band-pass filter operating at sampling frequency of 1MHz and center frequency of 250 kHz with a quality factor of 50. The proposed filter has both low-voltage and high speed properties of the auto zeroed integrators ...
متن کاملPV System with Virtual DC Bus for Cost Effective Grid Supply for Commercial Purpose
The main objective of this project to control the common mode leakage current by using virtual dc bus with PV systems. The power which we receive form the PV panel is not a constant supply due to various condition. In order to overcome this issue we are using Buck Boost converter for generating constant voltage supply to the inverter. The negative pole of the dc bus is connected directly to the...
