Design and implementation of a high speed low power 4-bit Flash ADC

This paper presents a four-bit flash type Analog to Digital Converter (ADC). The design is suitable for Ultra Wide Band (UWB) applications due to its high operating frequency and low power consumption. The high operating frequency is due to the pipelined nature of the design. The low power consumption is due to the minimized transistor sizes and modularity of the design. The proposed ADC is designed, integrated and simulated using Cadence EDA Tools. The simulation was done using a 3.3 V, 0.35 mum CMOS Technology.
