The IDE 4281 is an application specific integrated circuit (ASIC) that has been designed for the readout of CdTe/CZT radiation detectors in space. The chip can be used for single photon spectroscopy of x-rays and γ -rays with energy between 3.5 keV and 140 keV and rate up to 100 kcps per chip. The chip contains 12 low-noise pre-amplifiers (110 e equivalent noise charge, ENC), each followed by a pulse...
Differential Power Analysis (DPA) side-channel attacks pose serious threats for embedded system security. WDDL was proposed as a countermeasure that can be incorporated into a conventional ASIC design flow using standard cells. However, our spice simulations show that DPA attacks on WDDL still leak secret keys to adversaries despite the doubled area and energy overheads due to the use of complementary...
This paper discusses the problem of determining a thermal model of an electronic system based on the spectral analysis of its step temperature response. The proposed method yields equivalent RC Cauer ladder thermal models, which consist of only a few RC stages, but produce very accurate estimates of circuit temperature. Moreover, the values of model elements have physical significance. Such a thermal...
This paper presents simulations and measurements of an integrated PTAT sensor. The sensor is equipped with an overheat protection circuit and was implemented in an ASIC containing matrices of heat sources and junction temperature sensors. The PTAT sensor is used for temperature monitoring and it is responsible for issuing warning signals in a case of chip overheat. Particular attention is paid to...
This paper presents a practical realisation of the function specification inverse algorithm for real time integrated circuit temperature estimation. The algorithm was implemented in a test ASIC as a digital filter, which is capable of estimating heat source temperature values based on measurements taken by remote sensors. The operation of the algorithm is illustrated on simulated data obtained from...
As mainstream processing technology advances into 65 nm and beyond, many factors that were previously considered secondary or insignificant, can now have an impact on chip timing. One of these factor is inversed temperature dependence (ITD). As supply voltage continues scaling into sub-IV territory, delay-temperature relationship can be reversed on some cells, meaning that device switching time may...
Class D amplifiers are becoming the most feasible solution for embedded audio application. However, distortions due to the non-linear nature of switching stage are the main drawback for this amplifier topology. This paper discusses the design and implementation of high fidelity audio class D using sliding mode control scheme. This design method proves to be a cost effective solution for industrial...
