Cmos Integrated Analog To Digital And Digital To Analog Converters

IEEE International Solid-State Circuits Conference

Quantum-dot cellular automata (QCA) has come out as one of the potential computational structures for the emerging nanocomputing systems It has a large capacity in the development of circuits with high space density and dissipation of low heat and allows faster computers to develop with lower power consumption The QCA is a new appliance to realize nanolevel digital devices and study and analyze their various parameters It is also a potential technology for low force and high-density memory plans Large memory designs in QCA show unique features because of their architectural structure In QCA-based architectures, memory must be maintained in motion, ie, the memory state has to be continuously moved through a set of QCA cells These architectures have different features, such as the number of bits stored in a loop, access type (serial or parallel) and cell arrangement for the memory bank However, the decisive features of the QCA memory cell design are the number of cells, to put off the use of energy Although the review and study of the QCA-based memories are very important, there is no complete and systematic literature review about the systematical analyses of the state of the mechanisms in this field Therefore, there are five main types to provide systematic reviews about the QCA-based memories; including read only memory (ROM), register, flip-flop, content addressable memory (CAM) and random access memory (RAM) Also, it has provided the advantages and disadvantages of the reviewed mechanisms and their important challenges so that some interesting lines for any coming research are provided

Memory Designing Using Quantum-Dot Cellular Automata: Systematic Literature Review, Classification and Current Trends

Adiabatic Logic Future Trend And System Level Perspective

Analog-to-digital converters (ADCs) are needed in all those applications, which interface with the analogue world and exploit the digital processing of data. As digital processing is more and more gaining ground over analogue signal processing, the importance of ADCs correspondingly increases. The Flash type ADC, also known as Direct Conversion ADC, uses a bank of comparators, operating in parallel to achieve a high data conversion rate. In this paper, an area efficient low power high Speed 3-bit Flash Type ADC using bit referenced encoder is proposed in 180 nm CMOS technology. The concept of Threshold Modified Comparator Circuit (TMCC) is also introduced as a modification of the conventional comparator. The proposed design of the ADC occupies an active area of 0.0036 mm2 and consumes 43.146 µW of average power while operating with an input frequency (f in ) of 10 MHz and a supply voltage of 1.8 Volt.

Analog Comparator is designed to compare two analog inputs and outputs a logical signal indicating which of the inputs is greater or lesser. Comparators, being an essential building block of most high speed devices like Analogue to Digital Converters, are one of the most important components used in signal processing and communication systems. Also it plays a challenging role in high speed mixed signal system designs. In this paper, we have presented an ultra-high speed simple dynamic comparator design using 65nm UMC technology. The circuit is operating at a clock frequency of 6.66GHz and input signal frequency of around 3.33GHz. The propagation delay is minimized to about 47.14ps with a low noise of about 0.531fV2/Hz which makes the proposed structure favourable for Flash or Pipelined data conversion applications. However, it uses only a total of 12 MOS transistors with minimum W/L ratios to make the circuit simple and area efficient, without affecting its performance. With the enhancement of speed and keeping other parameters like power & energy at its optimum value, this comparator circuit is a novel design that can be used in any high speed applications.

Design of low noise high speed novel dynamic Analog Comparator in 65nm technology

As the conventional irreversible logic dissipates power for losing bits of information, computing engines has to be designed that do not require energy dissipation but only if computation is done logically reversible. Hence, research on reversible logic has been extensively increased now-a-days for its application in Quantum Computing, nanotechnology, QCA and Low power VLSI etc. In this paper, we have realized a Quantum Cost efficient Reversible RAM (RRAM) with a new 3×3 Reversible Gate named Modified Fredkin (MF). While approaching for RRAM we have also proposed a reversible D Flip-flop with minimum quantum cost (QC), a write enabled reversible master slave D Flip-flop & a (i × 2i) reversible decoder which has outperformed the existing designs in terms of quantum cost, ancilla & garbage outputs. We also have analyzed the architectures in terms of logical depth (worst case delay), hardly addressed in available literature.
