In this paper, a new single-stage input-currentshaping (ICS) technique that integrates the voltage-doublerrectifier front end with a dc/dc output stage is introduced. Due to the voltage-doubler-rectifier front end, the reduction of linecurrent harmonics can be achieved with a higher conversion efficiency compared to the corresponding single-stage ICS circuit with the conventional wide-range ful...

A new single-stage single-switch input-currentshaping (S4ICS) technique, which combines the boost-like input-current shaper with a continuous-conduction-mode (CCM) dc/dc output stage, is described. In this technique, the boost inductor can operate in both the discontinuous conduction mode (DCM) and CCM. Due to the ability to keep a relatively low voltage (<450 Vdc) on the energy-storage capacit...

Intake  is  a  concept  that  has  long  fascinated  second  language  researchers  as  it  provides  a window  onto  the  crucial  intermediary  stage  between  input  and  acquisition.  A  better understanding of this intermediary  stage can  help us to distinguish between input that  is used for immediate (e.g. communicative) purposes only and input that is drawn on for learning. This articl...

A real-time telemetry system, which consists of readout circuits, an analog-to-digital converter (ADC), a microcontroller unit (MCU), a graphical user interface (GUI), and a radio frequency (RF) transceiver, is proposed for amperometric and potentiometric electrochemical sensors. By integrating the proposed system with the electrochemical sensors, analyte detection can be conveniently performed...

Electron beam welding has shown a remarkable job in the space industry for welding of components. It is performed under a vacuum environment that eliminates foreign matter such as hydrogen, oxygen, and other gases. Joining of similar and dissimilar materials is the main advantage of electron beam welding with high depth to width ratio as well as sharp focus at the point where parts are to be we...

Cost-effective high-performance IR imaging cameras based on Quantum Well Infrared Photodetectors (QWIP) need CMOS readout structures which allow effective operation at temperatures compatible with inexpensive long-life coolers. At such high temperatures (around 72 K), the QWIP suffers from large background and dark currents (Fig. 1), which have a tendency to saturate the integrating capacitor i...

A noiseless multiple-input multiple-output (MIMO) channel operating under a strict complexity constraint at the receiver is introduced. According to this constraint, detected bits, obtained by performing hard decisions directly on the channel’s matched filter output, must be the same as the transmitted binary inputs. An asymptotic analysis is carried out using mathematical tools originated from...

A novel design technique employing CMOS Current Feedback Operational Amplifier (CFOA) is presented. The feature of consumption very low power in designing pseudo-OTA is used to decreasing the total power consumption of the proposed CFOA. This design approach applies pseudo-OTA as input stage cascaded with buffer stage. Moreover, the DC input offset voltage and harmonic distortion (HD) of the pr...
