چکیده
Absrmcf--This paper describes a 10 bit 50MSampleIs CMOS DIA Converter fabricated in a lpm single-poly double-metal CMOS process. About 30Y0 power could be saved in video application by using a modified look-ahead circuit. The INL is less than 0.46LSB, and the DNL is less than 0.03LSB in the power-save mode. The settling time to 0.1% is less than 2013s. At 50MS/s the SFDR is 60dB. I b i s D/A converter has a single power supply of 5V, and at 5OMS/s when the input is all zero dissipates 20mW and all one dissipates 25OmW. The core chip size is 1.4mm x 2.8mm.

Low-Power Adder Design for Nano-Scale CMOS
A fast low-power 1-bit full adder circuit suitable for nano-scale CMOS implementation is presented. Out of the three modules in a common full-adder circuit, we have replaced one with a new design, and optimized another one, all with the goal to reduce the static power consumption. The design has been simulated and evaluated using the 65 nm PTM models.
متن کاملLow Power, 3-bit CMOS Pipeline ADC with Reduced Complexity Flash Architecture
A 3-bit, 2-V pipeline analog-to-digital converter has been designed using a modified flash architecture. The developed circuit blocks of the modified flash analog-todigital converter, operating at 135MHz, are a fully differential comparator, a digital-to-analog converter and a sample-and-hold amplifier. The design technique of the N-bit modified flash ADC requires only 2 1) comparators as compa...
متن کاملLow-Power, Low-Noise Adder Design with Pass-transistor Adiabatic Logic
AbstraceIn this paper, the efficiency of a fully adiabatic logic circuit is compared with its combinational and pipelined static CMOS counterparts. The performance of each circuit is studied in terms of the maximum frequency of operation, the minimum voltage of operation, the circuit energy consumption, and the switching noise generated by the circuit. An 8-bit carry look-ahead adder is designe...
متن کاملDesign of power-efficient adiabatic charging circuit in 0.18μm CMOS technology
In energy supply applications for low-power sensors, there are cases where energy should be transmitted from a low-power battery to an output stage load capacitor. This paper presents an adiabatic charging circuit with a parallel switches approach that connects to a low-power battery and charges the load capacitor using a buck converter which operates in continuous conduction mode (CCM). A gate...
متن کاملHigh Speed-Low Power Radix-8 Booth Decoded Multiplier
This paper proposed a new method for adding sum and carry using carry look-ahead adder at the final stage of the radix-8 booth decoding multiplier. In a conventional radix-8 booth decoded multiplier, full adders and half adders are used to add sum and carry. After partial product reduction using booth decoding, the partial product rows are required to add for final result. In this method carry ...
