Abstract The paper presents a split-level sinusoidal power supply clock generator circuit for Two-Phase Adiabatic Static CMOS Logic circuit (2PASCL). The driving of adiabatic logic requires adiabatic controlled sources of voltage. We study the clock voltage generator circuit using SPICE simulation and investigate the most suitable scheme and highest energy efficiency for the energy recovery pow...
In this paper a novel very high performance current mirror is presented. It favorably benefits from such excellent parameters as: Ultra high output resistance (36.9GΩ), extremely low input resistance (0.0058Ω), low output (~0.18V) and low input voltage (~0.18V) operation, very low power consumption (20μW), very low offset current (1pA), ultra wide current dynamic range (150dB), and ultra high a...
Soft Switcing techniques have recently been applied in the design of dc-ac converters, in order to achive better performance, higher efficiency, and power density. One of the soft switching techniques uesd in inverters is resonant dc links. These topologies have some disadvantages such as irregular current peaks, large voltage peaks, uncotrollble pulse width, etc. Another soft switching method ...
The use of Universal type motors is very commonly used, both in daily life and research activities. universal motor can be used as prime mover generator PMSG (Permanent Magnet Synchronous Generator), which its application there are obstacles, namely the difficulty stabilizing speed due to influence changes load connected PMSG, this affects output voltage generated by system. In case, a stabiliz...

We all know that the basic building block of any communication system is the reference voltage generator. The objective of reference generation is to establish a DC voltage or current that is independent of the supply and process and has a well-defined behavior with temperature. Band Gap Reference (BGR) is one of the most popular reference generators. In the conventional BGR circuit, the refere...
The impact of wind energy generation connected to a weak grid is studied with SIMULINK as simulation platform. The wind energy conversion system is modelled by a squirrel cage asynchronous induction machine (ASM). The grid is modelled as an infinite bus. In the proposed system the ASM is connected to the grid through a DC-link with incorporated battery storage. An ultracapacitor (UCap) bank in ...
A new mixed-mode second order quadrature oscillator using two differential voltage current conveyors as active elements, two grounded capacitors and two grounded resistors each is proposed. The circuit provides several current and voltage outputs simultaneously. The circuit has low active and passive sensitivities. Non-ideal and parasitic study of the proposed circuit is also included. PSPICE s...
This paper, electronic resonant ballast for a small photovoltaic powered street lighting system in remote rural area was proposed. The street lighting system was designed for rural area where the electrical transmission line cannot be commonly serviced and it is the cascade systems of the solar arrays, switching battery charger, and electronics ballast with small fluorescent lamp. The ballast i...
