Radiation detectors were developed by depositing 20 μm thick hydrogenated amorphous silicon (a-Si:H) sensors directly on top of the so-called aSiHtest integrated circuit. This circuit was designed in a quarter micron CMOS technology as a global test circuit for this novel detector technology. The sensor leakage current turned out to be limiting the performance of the whole detector. Its detaile...

The capabilities of Horizontal Current Bipolar Transistor (HCBT) technology for radio frequency (RF) integrated circuit (IC) design is analyzed. The HBCT, with its novel technological approach and integration with existing CMOS technologies, is entering the testing phase on IC level. The demanding RF integrated circuit requirements and design issues in the frequency range 0.9 – 5 GHz are presen...

Until recently, integrated circuit design was based on the following contract between design andmanufacturing: designs are to follow a set of manufacturing-driven constraints (commonly known as ‘design rules’), and manufacturing is to meet the performance and yield targets in producing the specified design. This arrangement worked for many years until the designs of sub-100nmnodes came along, w...

a high accurate and low-voltage analog cmos current divider which operates with a single power supply voltage is designed in 0.18µm cmos standard technology. the proposed divider uses a differential amplifier and transistor in triode region in order to perform the division. the proposed divider is modeled with neural network while tlbo algorithm is used to optimize it. the proposed optimization...

Almost a decade after the invention of the first semiconductor transistor in 1948, it took around a decade for the revolutionary technology to evolve from producing single devices to the integration of a few transistors as the first integrated circuit in 1958. Since then, integrated circuits have been in continuous progress for more than half a century as predicted by the well-known Moore’s law...

Realization of a novel single-resistance-controlled oscillator, employing an active element and all grounded passive elements, is the purpose of this manuscript. With requirements for completing the design being only a single Voltage Differencing Current Conveyor and four grounded passive components, it is also a preferable choice for integrated circuit implementation. The designed circuit has ...
