In the field of analog signal processing, there is a strong need for low-voltage and low-power integrated circuits. Especially in the mobile communication circuitry, an analog signal processing circuit must be fed by dry batteries of 1–1.5 V. This paper presents a design and implementation of a current-mode fully-differential analog CMOS integrator operable with such a low supply voltage. This ...
The cycle-by-cycle power differential determines the noise introduced due to inductive ground bounce. However, very few attentions are paid to minimize the cycle-by-cycle power differential in high-level synthesis stage. In this paper, we investigate the simultaneous application of operation scheduling and operation delay selection for minimizing the cycle-by-cycle power differential. An intege...
determination of volume change of unsaturated soils during loading and suction change is one of the most important difficulties in testing unsaturated specimens. it is revealed from literature review that various attempts have been made to invent an apparatus that can be used in testing on unsaturated soil specimens, simply and accurately. in this research, details of design and manufacture of ...
Herein we report a case of primary leiomyosarcoma of testis, which was believed to originate from normal testicular structures. It contained smooth muscle cells, blood vessels and contractile cells of the seminiferous tubules. No evidence of tumor spread was found.Treatment consisted of orchiectomy with high ligation of the spermatic cord. The patient received no adjuvant therapy and there w...
This paper describes a CMOS transconductance element based upon two differential pairs whose outputs are summed to give a linear transfer characteristic. The circuit has been simulated using a 2pm process from MOSIS, and results show that with a single 5V supply, bandwidth in excess of 300MHz, THD below 0.7% for a lV,,k-,,k differential input signal, and dynamic range in excess of 70dB can be a...
A fully differential transimpedance amplifier has been designed and implemented in 0.18 μm standard digital CMOS technology. The parallel feedback circuit topology is adopted to broaden the bandwidth. It can operate at 10 Gb/s with the dynamic range from 25 μA up to 2.5 mA. The power consumption is only 88 mW under 2 V supply voltage.
In this study consideration is made of the common mode (CM) behavior of two-stage fully differential amplifiers in voltage feedback connection. In particular, interaction between internal CMFB circuitry and the external feedback network is investigated in order to highlight a possible operating point instability condition, due to the presence of a positive feedback loop. Two alternative CMFB to...
We report the first kinematically complete study of the four-body fragmentation of the D2 molecule following absorption of a single photon. For equal energy sharing of the two electrons and a photon energy of 75.5 eV, we observed the relaxation of one of the selection rules valid for He photo-double-ionization and a strong dependence of the electron angular distribution on the orientation of th...
