Abstract Analog-to-digital converters ADCs are used in all communication systems. The sampling rate of such ADCs are directly related to the system data rate. The ultra-wide UWB system is on of the newest proposed wireless technology. This system is targeting wireless transmission of video, high-quality audio and other high-bandwidth data which makes it possible to enjoy the complete wireless freedom in a short-range environment.

Since the system proposes the transmission of high data rate, the ADC sampling rate requirement for this system is very high in the order of 1 GHz. However, the flash implementation suffers from two important drawbacks.

For ADC resolution higher than 2-bit the silicon area is huge and the power consumption is very high.

These disadvantages make it impossible to implement flash ADC on an integrated solution for the whole system or at the least at the RF part. This paper investigates the possibility of overcoming the disadvantages of a standard flash ADC realization.

The paper proposes a solution where the flash ADC uses only inverters for its comparators. With this simple realization, a very high speed an high resolution ADCs can be manufactured with low power consumption and small silicon area.

This implementation seems to be the best fit for the UWB system. A complete ADC block for the UWB system is design based on the inverters-only flash topology and the simulation results are meeting the requirements of this high speed wireless communication.A THESIS Submitted in Partial Fulfillment of the Requirements for the Degree of CONTINUOUS DIGITAL CALIBRATION OF PIPELINED A/D CONVERTERS By Alma Delic-Ibuki´ c´ instrumentation require high-speed, high-resolution Analog-to-Digital Converters (ADCs).
