The Radiation Hardened Electronics for Space Environments (RHESE) project consists of a series of tasks designed to develop and mature a broad spectrum of radiation hardened and low temperature electronics technologies. Three approaches are being taken to address radiation hardening: improved material hardness, design techniques to improve radiation tolerance, and software methods to improve ra...

This document describes the evaluation of a 200MHz analogue-to-digital converter acquisition evaluation board. The evaluation board contains an AD9410 10-bit ADC [1], which was purchased from Analog Devices for $200. The evaluation board is interfaced via an Altera APEX FPGA to a custom capture card [2]. The APEX FPGA currently contains minimal logic for synchronizing the two data streams from ...

To date, al1 published CMOS field-programmable analog array (FPAA) designs have operated under lMHz bandwidths. This thesis develops circuit methods allowing the development of a CMOS FPAA operating at greater than lMHz frequencies. For this purpose the secondgeneration current conveyor (CCII) is used. IC test results of a O.8p-n CMOS chip containing four configurable analog blocks based on the...

This paper presents a soft-switching DC-DC boost converter, which can be utilized in renewable energy systems such as photovoltaic array, and wind turbine connections to infinite bus of a big power network, using grid connected inverters. In the proposed topology for the DC-DC boost converter, the main and the auxiliary power switches are turned on and turned off with zero voltage switching (ZV...

In recent years, satellite communication has gained increased prominence and driving factors are the reliability, new design techniques and reduced cost. The onboard control system components of the satellite are subjected to high temperature, shock and vibration both during initial transport and launch, and also during periodical orbital corrections. These effects can introduce faults in the c...

A reconfigurable current mode programmable multiphase sinusoidal oscillator is realized using digitally controlled low voltage CMOS current conveyors. The realized current mode programmable multiphase sinusoidal oscillator can provide independent digital control to its oscillating frequency through n-bit control words with high resolution capability, as well as reconfigurability. The realized m...

In recent years, thermal sensing in digital devices has become increasingly important. From a security perspective, new thermal based attacks have revealed vulnerabilities in digital devices. Traditional temperature sensors using analog-to-digital converters consume significant power and are not conducive to rapid development. As a result, there has been an escalating demand for low cost, low p...

In some applications it is important to detect the QRS complex in the ECG waveform with possibly low time delay. Traditional software detectors of the QRS complex implement algorithms usually based on cascades of digital filters that introduce delays up to parts of a second. On the other hand, hardware QRS detectors fulfil the low delay requirements, but have worse adaptive features for the cha...

In the paper, an instrument for simultaneous measurement of active, reactive and apparent power is presented. Its functionality is based on a PWM intermediary conversion multichannel analog to digital converter (ADC). The instrument is implemented on an Altera’s Flex10k70 Field Programmable Gate Array (FPGA) device for single phase. It fits roughly 60% of logic cells without any resource sharin...
