A novel active feedback frequency compensation scheme is presented in this work. Based on the proposed technique, an amplifier with two main poles in its frequency bandwidth can be easily compensated by introducing a pole-zero pair in a local feedback. The proposed method is mathematically analyzed and then based on the derived formulations, a design procedure is established. The capability of ...

The 2-dimensional logarithmic number system (2DLNS), a subset of the multi-DLNS (MDLNS), which has similar properties to the classical Logarithmic Number System (LNS), provides more degrees of freedom than the LNS by virtue of having two orthogonal bases and has the ability to use multiple 2DLNS components, or digits. The second base in 2DLNS can be adjusted to improve the representation space ...

objective: yield components and genetic contribution have the most important in final yield and breeding programs of crop plants. for this purpose, 20 varieties of grapevines with russia origin were evaluated in urmia and takestan research station (under full irrigation and drought stress). methods: twenty grapevine genotypes were evaluated in urmia and takestan research station (under full irr...

performance of the fiber optic networks with different physical topologies such as point-to-point, bus, ring and star, with respect to requirements as bit rates, topology structure, bit. error rate (ber) and optical component characteristics including optical amplifiers, filters, sources and detectors, are analyzed and simulated. for this purpose, maximum number of supportable nodes and throug...

The reliable operation of SRAM in presence of process variation in sub-100nm devices is largely influenced by periphery circuits, like sense amplifiers, demanding more robust solutions. A new differential sense amplifier for use in standard 6-T SRAM based on gated-diode is proposed and designed. For comparison, three other latch-based sense amplifiers are also designed in 45nm technology. The b...

In this paper we present an ultra low-voltage (ULV) floating-gate (FG) transconductance amplifier The amplifier can operate at supply voltages below 1V in a standard digital double poly CMOS process . The amplifier consists of a sinh shaped output current transconductance amplifier and a tanh shaped transconductance amplifier.
