After seeing the technological evolution, we have understood about the A/D converter that it is the meeting point of the analog to digital domains. As technology is being continuously scaled down, the transistor sizes have decreased drastically resulting in reduced area and power consumption in the digital domain. The successive approximation ADC is best suitable for low power applications with moderate speed and simple design. Here, the implementation of 32-bit pipelined analog-to-digital converter with the help of successive approximation register based Sub-ADC. The SAR ADC architectures are popular for achieving high energy efficiency and low power applications. But they suffer from resolution and speed limitation. To overcome the speed limitations of SAR ADC, we proposed the implementation of 90nm using CMOS technology of a low power, high speed pipelined analog-to-digital converter (ADC). The capacitive digital-to-analog converter (DAC), two stage CMOS comparator with output inverter of proposed ADC are lower than those of a conventional ADC. To achieve low power and to minimize the size of the input sampling capacitance in order to ease durability.

The One

In this paper, a novel architecture for self-timed analog-to-digital conversion is presented and designed using the NULL Convention Logic (NCL) paradigm. This analog-to-digital converter (ADC) employs successive approximation and a one-hot encoded masking technique to digitize analog signals. The architecture scales readily to any given resolution by utilizing the one-hot encoded scheme to permit identical logical components for each bit of resolution. The four-bit configuration of the proposed design has been implemented and assessed via simulation in 0.18-μm CMOS technology. Furthermore, the ADC may be interfaced with either synchronous or four-phase asynchronous digital systems.
