Design Low Power Encoder for Threshold Inverter Quantization Based Flash ADC Converter

Low Power Flash ADC

In this paper, a new design for a low power CMOS flash Analog-to-Digital Converter (ADC) is proposed. A 6-bit flash ADC, with a maximum acquisition speed of 1GHz, is implemented in a 1.2 V analog supply voltage. HSpice simulation results for the proposed flash ADC verifying the analytical results are also given. It shows that the proposed 6-bit flash ADC consumes less power i n a commercial 90n...

Low Power Encoder and Comparator Design of 5-bit Flash Adc

High-Speed and Low-Power Flash ADCs Encoder

This paper presents a high-speed, low-power and low area encoder for implementation of flash ADCs. Key technique for design of this encoder is performed by convert the conventional 1-of-N thermometer code to 2-of-M codes (M = ¾ N). The proposed encoder is composed from two-stage; in the first stage, thermometer code are converted to 2-of-M codes by used 2-input AND and 4-i...

A SoC based low power 8-bit flash ADC in 45 nm CMOS technology

In modern VLSI design the transistor sizing and scaling has an considerable impact. There are very essential two constrains, which needs serious attention to the VLSI chip designer are high speed and low power consumption. Therefore in this paper an 8-bit 3 Gs/sec flash analog-to-digital converter (ADC) in 45nm CMOS technology is presented for low power and high speed system-on-chip (SoC) appli...

A 3-Bit Pseudo Flash ADC Based Low-Power CMOS Interface Circuit Design for Optical Sensor

The paper presents a CMOS interface circuit design for optical pH measurement that can produce an 8-bit digital output representing the color information (i.e., wavelength, l). In this work we are focusing at reducing the component count by design and hence reducing the cost and silicon area. While it could be further optimized for lower power consumption, the proposed design has been implement...
