In this paper an optimized hardware co-simulation approach is presented to design & implement GSM based digital down convertor for Software Defined Radios. The proposed DDC is implemented using optimal equiripple technique to reduce the resource requirement. A computationally efficient polyphase decomposition structure is used to improve the hardware complexity of the overall design. The propos...

This paper presents 10-bit, 1.5 MS/s, 2.5V, Low Power Pipeline analog to digital converter using capacitor coupling techniques. A capacitance coupling foldedcascode amplifier effectively saves the power consumption of gain stages of ADC in a 0.25 μm CMOS technology. The ADC also achieves Low power Consumption by the sharing an op-amp between two successive pipeline stage further reduction of po...

This letter presents a compact metamaterial-based tunable zeroth-order resonant antenna. It is based on the double-negative unit cell with a function of tunable inductance realized by a varactor and impedance convertor in the shunt branch. The resonant frequency of the designed antenna ranges from 2.31 to 3.08 GHz, depending on the capacitance of the used varactor. Its size is very compact (0.0...

Flash Analog to Digital Convertor (FADC) is frequently used in nuclear and particle physics experiments, often as the major component in big multi-channel systems. The large data volume makes the optimization of operating parameters necessary. This article reports a study of a method to extend the dynamic range of an 8-bit FADC from the nominal 2 value. By comparing the integrated pulse area wi...
